I have seen many threads here on RPF dealing with buying coins and other forms of PM's in traditional methods yet I have never seen anything dealing with buying these at public auction. So since I am a professional auctioneer I thought I would use my experience and knowledge in the subject to help some of my fellow liberty activists out.

WHAT IS AN AUCTION?

Believe it or not, some people are totally unfamiliar with what a public auction is so for those of you who fall into this catergory here is a bit of a background on what they are and how they operate.

It is said that auctions are the second oldest business on earth. Auctions have been held since the beginning of recorded history and you can literally auction off anything including coins and other forms of precious metals. The purpose of an auction is to offer the good or goods up for sale to the highest bidder (whoever agrees to pay the highest price on an item will become the owner of said once the auctioneer says "sold") They serve as a means of quick liquidation of all goods held by a business or person.

Public auctions are held either at galleries owned by the auction company or at public locations such as fire houses, hotel banquet rooms or fair grounds. Auction companies will announce the date, sale and terms of the auction (more on terms in a bit) usually 2-3 weeks in advance unless it is expected to be a multi million dollar auction which could be announced months in advance. You will find announcements for sales in traditional formats such as newspapers and other classified publications and in modern times you will find the majority of auctions listed online through websites such as www.auctionzip.com and other websites of that ilk.

Prior to an auction, there will be what is called a "preview" which will allow you to enter the facility and examine items for sale. This preview period depends on the auction company and the location. Some will have a preview of only a few hours while some will have preview periods that can last days. Most advertisements will list the time and date of previews and if not you can find out with a quick call to the auction company.

On the day of the sale (and after previewing the items) you will need to register with the auction company and get a bid number (this number will identify you to the auction company so that your purchases can be tallied at the end of the sale). At this time you will need to ask the registration clerk what the order or sale is (more on this later). When the auction begins, the potential bidders will assemble and the auctioneer will begin to sell the items. Auctioneers sell the items at a rapid pace (good auctioneers can sell between 75-100 lots an hour) and you will need to pay special attention to what is being sold and what the current price is. When the last item you are interested in has been sold you will go see the checkout clerk and present them with your number so that they can get a tally of all of your purchases and with that you will be done. At the end of the day you should have acquired some items that were far undervalued and if nothing else, you spent only a few hours time and had a decent night.

HOW DOES THIS APPLY TO PM'S?

Most auctions will have at least one item that is made from precious metals and some of these items are ones you would not think of from investment purposes. The most often encountered form of precious metals at auction is coins though you can acquire PM's through buying antique items made from coin silver, candlesticks,pocket watches, bars of precious metals (these come up more than you might think), jewelry and sometimes just oddball items made from precious metals (I once encountered a miniature russian bear figurine made from solid gold). If there is enough interest in this or a desire to know more about how to identify antique and vintage items made from precious metals than I will do a thread on that as well but for now I will stick with coins since they are the most often encountered.

HOW TO BUY COINS MADE FROM PM'S AT PUBLIC AUCTION

One might think that you cannot find true bargains in pm's when other people are allowed to bid but that is far from the truth. There are various tips and tricks you can use to increase the odds of you finding precious metals for next to nothing. First, knowing the type of auction you will be attending is key. A general rule of thumb I use is "the smaller the auction the better the odds". Auctions that are just starting out in the business or auctions that run on a very infrequent basis (this will require a bit of research on your part) almost always attract much smaller crowds than auctions that have an established, regular business. Obviously the less people you have to deal with, the better your odds will be of getting something as cheap as possible. Finding auctions in rural areas will be your best bet for this so it may require an investment of time and travel for those of you who live in and around metro areas but it could pay off big time for you.

There are many exceptions to this rule though as bigger auctions attract very serious dealers and collectors. Dealers and collectors will be very familiar with the established auction firms and will show up in droves to buy mass quantities of coins but the saving grace here comes with the knowledge that those interested solely from the investment standpoint will typically not waste their time hitting an auction with only a case or two of coins. At the established auction houses you will see rare or desireable coins in good condition going for over book value on a regular basis however, there will always be coins that are in a condition that leaves them unappealing to the big bidders. The dealers and collectors want coins that are of the highest grade possible and will routinely ignore coins that have a tarnished look or that do not have a highly desireable year or mint mark. Many of these coins will be silver and will have the same meltdown value as those coins they just spent an ungodly amount of money on and here is where you can really make a sound investment or a quick profit. With the undesireable coins, auctioneers will routinely group them into a lot (more on this in the terms and definitions section) and you will be able to buy them for a low price. For example, I have often been able to buy stacks of Morgan silver dollars for as little as $2 simply because they were deemed "ugly" or "junk" by dealers and collectors.

Estate auctions are also a great place to find coins and a great place to buy them. Estate auctions are notorious for having antique dealers and little old ladies looking to buy up fabrics and glass but they will rarely draw serious investors in precious metals. Almost every estate I have ever handled has had coins in it to some extent and you never know what is going to come out of an estate. Even if you do not see coins listed in the advertisement it is worth it to go during the preview or at the very least give the auction company a call. Many auction companies either pay for advertising out of their pocket or charge only a fraction of the advertising cost to the consignor so they try to fit as much into as few words as possible. Unless they know that a coin is rare or valuable they will often times not even mention them or just list them as simply "coins" in the advertisement. You would not believe how many estate auctions I have attended in the past whose advertisements made a big deal out of duck decoys, John Deere memorabilia, depression glass etc but said nothing at all about the coin collection that was part of the estate and is being sold that night.


TIPS & TRICKS FOR SUCCESS

Read the terms and conditions of the sale first and foremost. Does the auction company charge a buyer's premium? Is the auction going to accept telephone or internet bids? Is the auction listed as an absolute auction? I will delve into what these mean in the terms and definitions part at the end of this but be aware of what you are walking into.

Get to know the auctioneers and auction staff. Most auctioneers are not experts or even enthusiastic about the stuff they sell and while it may seem ridiculous (and it is) many auctioneers do not go out of their way to learn everything about the items they sell or to become skilled in the art of appraisal. So get to know who you are dealing with. Is this an auctioneer who knows a lot about valuable merchandise or is it in auctioneer who views it as only a job and would rather talk about Nascar than discuss the content of standing liberty quarters? It helps to know this about auctions you plan on attending on a frequent basis as it will give you an idea even before you walk in as to what the odds are of finding PM's at any given sale. For example, if you know the auctioneer has a lot of knowledge yet you do not see any listing for anything that could be made of PM's than you will know you might be wasting your time. If you know the staff are morons than you will know that they were either too ignorant or too lazy to bother listing, researching or looking at their items ahead of time.

Get a good price guide and keep it in your vehicle. Even if you are not going to buy as a coin collector but simply buying as a PM investor you should get one. The good guides will not only list the price but will also list the metallic content of the coins you are interested in. A quick trip to your car will let you know very quickly how high you should really go on those coins.

Become familiar with the big collectors and dealers in your area that attend these auctions. Many times they have purchased what they consider "junk" coins that were lotted with something more desireable and will be more than happy to sell these in bulk to you for next to nothing and will consider you a sucker for buying them. Remember, many collectors and dealers are only interested in the highly collectible coins and do not stop to consider the meltdown value of those "junk" coins.

Know what YOU are before bidding. If you are only interested in being an investor in PM's than avoid that temptation to buy those rare, great condition pieces (no matter if it is a coin or not) and stick solely to the "junk". Once you start buying the high dollar stuff you are no longer a mere investor because you have crossed the line into a collector.

Do not make the mistake of seeing an auction listing (either in a print advertisement or in the more detailed listings on an auctioneers website) that has coins and think they are all desireable and not go. Remember, time and money is precious to auctioneers and they will generally not waste time or money by listing what they know will not bring in big money bids. If you see coins, they will almost always have more than what is listed.

If you know you are going to be there awhile it might be wise to pack your drinks into a cooler with some ice. Auction houses sometimes make more money from concessions than they to do from their consignor fees. You will save a lot of money just taking your own and keeping it in your car.

Take a fanny pack, briefcase, lock box, etc with you. Public auctions (especially those that are poorly organized) can be a hotbed for theft. You would be amazed how many people put something into a box beside them to bid on something and find items they purchased earlier in the evening are now gone. So take something that you can keep on you at all times or something you can lock up. If you do this, be sure to place a tag on it identifying it as your personal property and not an item that was for sale and be sure to alert the auction staff to the fact that you are bringing it into the facility as your property.

Stay away from specialty coin auctions (auction houses that only deal in coins and currency). This may sound stupid but those auction houses are already very well known and very well attended by investors along with dealers and collectors and the odds of getting a steal on anything are slim and none.

KNOW BEFORE YOU GO/ TERMS & DEFINITIONS

Some terms relating to the auction business can be confusing for someone who does not attend on a regular basis or someone who might attend for their first time. To help you along, get to know these terms as they will help you a lot.

BID - The amount you have agreed to spend to purchase the item.

BIDDING - The act of placing a bid on an item or group of items.

ESTATE AUCTION - When a person passes away their items will often go on the auction block either through the wishes of the family or through the order of a probate/orphans court. Many times, these sales will include virtually everything a person has accumulated through their life and sometimes will even include the sale of their house or property.

ON SITE AUCTION - These auctions are typically always held in rural locations where parking is possible because they are held right on the person's property. You will most often see this when the person's house or property is also being auctioned off or when there are too many items to reasonably transport to an auction gallery.

LIVING ESTATE AUCTION - These sales are the equivalent of a garage/yard sale and it is up in the air as to if you will find any good pm's at these. These are usually held when someone is moving or at the order of the court because of a divorce or family feud.

ABANDONED PROPERTY AUCTION - This will usually be an auction of an abandoned or delinquent storage lot. You will very rarely find PM's at these sales though stranger things have happened.

BUSINESS LIQUIDATION AUCTION - These are usually held when a business is going out of business or through court ordered bankruptcy proceedings. Unless the business in question was a coin shop or an antique shop, the odd's of finding PM's of any type are not good at all.

BUYER'S PREMIUM - Be cautious of how much you spend when you encouter an auction that is charging a buyer's premium. This simply means that the auction house is going to charge you a certain percentage more than your highest bid as a type of service charge. These charges can be as low as 5% or as high as 45%. If at all possible, avoid auctions that charge a buyer's premium but if you cannot do that than be aware of what they charge and add that percentage on top of each purchase you make so that you do not go over budget accidentally.

ABSOLUTE AUCTION - Absolute auctions are sales where no item features a reserve price and every item will be sold to the highest bidder. If an auction is not listed as an absolute auction than there will be items that have a reserve. It is best to contact the auction house to verify this as some auctioneers never think to list their auctions as absolute.

RESERVE - Reserve means that the auction house or the consignor (usually the consignor) has set a certain price that a specific item cannot sell under. I would typically avoid these sales as they are very irritating.

AS IS WHERE IS - This means that the auction is offering no refunds, rerurns or exchanges and that all sales are final.

SOLD - We all know what this means but in auction terms, the sale of an item is not complete until that auctioneer yells sold. A person can bid against you until the second that happens

MINIMUM BID - Many auction houses are now using minimum bids and for most auctions that amount is $1 or $2.

LOT - If an auctioneer cannot get the house minimum bid on an item they will often lot it up which means they will take another item from the same consignors group and offer it along with the item they could not get a bid on. In regards to PM's you will see this a lot with junk coins. They will grab handfulls and offer them all for one price. Lot can also mean the entire grouping of a person's consignment. You will notice that sometimes an auctioneer will say "lot 18" or some other number. This simply means they have moved to a different grouping by a different consignor. Same word but different meanings.

TELEPHONE BID - A bid made by a registered bidder who registered over the phone and is bidding through a proxy bidder.

INTERNET BID - A bid given by a registered bidder over the internet either through e-mail or in real time through a proxy bidder.

PROXY BIDDER - A person (almost always an employee of the auction house) who bids on behalf of those who cannot be at the sale in person. I would generally avoid an auction house that accepts bids through proxy bidders too much as it is very irritating.

ORDER OF SALE - The order of sale simply means the order in which the items will be sold. This will vary by auction company and it is best to ask about this before the auction starts. Some auctions will have just one auctioneer going while some will have multiple so it is important to know this in order to not miss any bids that you wish to make.

FINAL NOTES

Even for those of you who are not investors in PM's auctions can be a great way to save a lot of money. You can literally buy anything from furniture for your home for only a few dollars on up to seeds, plants, livestock and tools all for next to nothing. They are great sources if you are hoping to get off the grid or even if you want to just save a ton of money.
 
I had a friend tell me the other day about buying up contents of storage units that go up for auction. Have you heard of this and how legit is it? He said you get some winners and some losers but overall was a good deal.

EDIT: Great read by the way. I had something on the top but I must have deleted it.:D

Yeah I put something about storage or abandoned lot auctions in the original post. Basically, they can be good for antique dealers or people looking to furnish a home but you typically do not find anything of tremendous value in abandoned storage lots (there are always exceptions). Most people keep PM's at home and do not store much made of gold, silver, platinum, palladium, etc in storage bins but if you are not solely concerned with buying up PM's than storage auctions can be a lot of fun :)
 
That's flipping excellent, Jimmy. You should rewrite it for an audience that knows how auctions work and see if Antique Week will pay you for it. It's timely, and right up their alley. Connie is always looking for good stuff to print.

ETA: I'd like to know more about how to buy jewelry at auction. I've been to about a hundred auctions, but never been brave enough to buy jewelry.

Ty so much for the compliments. I have actually written freelance stuff for several industry publications before but many of them are not currently paying for freelance content anymore but doing some additional works is not out of the question in the future.

When you say you would like to know more about buying jewelry, do you mean knowing more about the types of marks to look for and how to distinguish real gem stones from fakes or do you mean what type of auctions to get the best prices on fantastic pieces?
 
For those that doubt this works, I have a friend who went to an auction near Baltimore tonight and bought a bag of 45 nasty looking 1oz silver eagles for *drumroll please*......$30.

He is one happy camper!

Well, both :) - but usually I fear buying fakes, so what to look for would be very helpful.

ETA: my favorite auction tricks:

If you don't have your eye on a particular item, it's ok to skip the beginning the auction, but be sure to around until the end. A lot of bidders leave after a few hours. As the evening starts to drag on, the hammer comes down faster and a lot of items go for a fraction of what they would have gone for earlier in the day.

Terrible weather (especially snow) can mean a horrible turnout for an auction. I attended an auction once, and only 3 other people showed up. The auctioneer let us choose what items came to the block, because he didn't want to waste time on items that weren't going to get bids, and we got a whole van full of stuff for $20.00.

This ^^
There are rumors of high tech saws that will cut the front and back faces off of coins. Then counterfeiters will wrap an alloy with these faces. I don't know if it is true, but I just heard about it.
 
Wow. That was really informative and helpful.

I really appreciate the write-up. I'm gonna go look for an auction.

:D

Thanks, I'll get it done! You guys are so helpful. Yesterday I learned about buying and selling websites and today I learn about auctions...I friggen love this place.

I have found an auction I will be going to tomorrow morning. It will be my first auction ever. I have followed the OP advice and contacted the auctioneer with all of my questions, he too was rather helpful.

The auction listed "Coins: 20 Morgan & Peace Silver Dollars; 6-Barber Coins; Silver & Clad Kennedy Half Dollars; 10-Proof & Mint Sets; 50-Indian Head & 50-Wheat Pennies..." According to coinflation.com the morgan and peace dollars are almost $17 a piece.

Also, I was worried that many people would show up, but it's harvest time in Indiana and this auction is located in the heart of corn/bean country. However, Indiana is waaaayyy ahead of schedule for this years harvest so maybe they will be taking a break and come to the auction. IDK, worst case it's a learning experience.

I'll let you all know how it goes.

Thank you, thank you, thank you to all my friends at the Liberty Forest!!!
 
My pleasure to assist! I will give a lot of information here (most of which you will probably already know) so that if anyone else is interested I might cover the questions they would have as well.

Jewelry can be tricky business but there are quite a few ways which you can avoid being burned on the auction block. First I can give you a good list of tools that you should acquire and keep in your car at all times.

TOOLS

Jeweler's Loupe - These can be purchased online for as little as $14.99 and I would suggest getting one that you can hang around your neck with at least 25x magnification capabilities. These are very important as many times it is almost impossible to see the makers mark or other important marks that may be on the piece in question. These will also allow you to spot possible damage areas such as old breaks or modifications of bands, chips in stones, etc.

BABY WIPES - This may sound stupid at first but many times (especially at estate sales) you will encounter jewelry that has not been cleaned in decades and in order to do some of the tests that will follow, you will need the item to be clean.

PEN BLACKLIGHT - These can be purchased for about the same amount as a respectable loupe. Many modern chemicals (and even old chemicals) used in jewelry repair and alteration will glow when exposed to blacklight so even if it is not visible with a loupe you will want to scan a potentially valuable piece with a blacklight (tip.. this also works with antique textiles, glassware and artwork).

PEN FLASHLIGHT - Many auction galleries will have poor lighting and this will assist you with viewing the piece in question in low light areas. This can also be used to test the refractive quality of certain stones which can help determine authenticity.

LASER TESTER - This is not absolutely necessary and they can be very expensive but if you plan on becoming a major estate jewelry buyer than this will save a lot of time and effort. A great one will be able to test for silver, gold, platinum, palladium, diamond, onyx, ruby, emerald, pearl, mother of pearl, etc. I will give you other methods to test for these items as one of these units (a good one anyway) is typically out of reach for the casual dealer.

A LIGHTER - Some types of jewelry can be tested with heat and you can use a lighter in combination with the next tool which is a:

SEWING NEEDLE - Some types of jewelry can be tested by poking it with a hot needle.

MAGNET - You can use a small magnet to test for authenticity of certain types of metals.

Now that you have a breakdown of basic tools you will need, we can move on to different types of jewelry you will encounter.

TYPES

PRECIOUS STONES - For the purposes of this I will focus on the most commonly encountered which are Diamond, Ruby, Emerald, Onyx, Opal, Amethyst and for the sake of time and space I will include pearl in this.

PRECIOUS METALS - You will find many basic bands, chains as well as necklace and bracelet charms of made of either gold, silver or platinum and since those are the most common, I will stick with those.

COSTUME JEWELRY - I will include some info on some of this because there are some very collectible costume jewelry pieces made from certain non precious materials and there are ways to determine the real deal from the fakes.

Those are the three major types of jewelry you will encounter and virtually everything you see will fall into one or two of those categories. So now we can move into the details of how to tell the valuable from the junk.

DIAMONDS

Diamonds can be scary to get into but there are a few tips and tricks which really help. The first rule of thumb to use is what I call the compatability test. If it looks like a diamond but it is on a silver band or a gold band of less than 14k than the diamonds are either really small or they are not real. Jewelry makers going back to ancient times have put precious stones on precious metal bands and it is rare that you see a quality stone on a non precious metal or a high quality precious metal band. This rule applies to all precious stones and precious metal bands with stone placements.

THE CUT TESTThe first tip is obvious. We have all heard that real diamonds can cut glass and this is true but modern cubic zirconias are made so well that they can do the same thing so this tip only applies to true antique pieces. I would reccomend this as a last resort because you run a real risk of damaging the stone.

THE READING TEST - Because of the refractive nature of natural diamonds, you cannot clearly read through them whereas with fake stones you can. If you can clearly read something by looking at it through the stone than you do not have a real diamond.

FOG TEST - Natural diamonds do not conduct heat so if you breathe on a stone and it remains foggy for more than a second or two than you do not have a real diamond.

WEIGHT TEST - This one can be tricky but you can practice and learn to feel the difference. CZ stones have a greater density than natural diamonds and thus a CZ stone that is the exact same size as a natural diamond will weigh slightly more than the diamond. Through practice you can learn to tell the difference.

FLUORESCENCE TEST - This is where you can make first use of that blacklight pen. When held under a blacklight, a CZ stone will not cast a real noticeable blue fluorescence whereas a natural diamond will give off a blue fluorescence. The one drawback here is that the better quality the diamond the less of a blue hue you will see so if you examine a piece and you do not see a real brilliant fluorescence yet you still feel that it could be the real deal than go to other testing methods.

LOUPE TEST - You can use a loupe to inspect the girdle of the setting. The girdle is where the stone's pavillion (the part of the stone hidden by the setting) and crown (part of the stone above the setting) meet. If this area looks somewhat frosty in color under a loupe than you likely have a real diamond however it it looks sort of waxy in that area under the loupe than the odds are that you are looking at a fake. You can also use a loupe to look for a dead giveaway with CZ stones and that giveaway is that many modern CZ stones are almost microscopically engraved or laser etched "C.Z." inside of the stone. If you see that mark than you know you are dealing with a cubic zirconia.

PAVILLION TEST - This is not 100% but more often than not it holds true. If you look at the pavillion of the setting (again, the area of the setting that hides the bottom of the stone) you should see it has a hole cut into the metal. Jewelry makers cut the very bottom out for diamonds because they want it to catch as much light as possible, making it sparkle. With CZ stones they rarely do this.

RUBY

There are not as many ways to determine real rubies from fakes but the good news is that you are not as likely to run into fake rubies on the auction block though they certainly do exist. Here are a few tips to help you determine the real deal from the fakes or the lab created.

CUT TYPE TEST - Almost all rubies over 1 carat are cut in oval or cushion cuts. It would help to get to know the different types of cuts before you go out as this is the number one indicator between the real deal and faux stone. If you are looking at a big stone with a simple cut than it is not a ruby.

PAVILLION TEST - Rubies like diamonds will only rarely feature a closed pavillion. Most of them will come with open backs where you will see a small hole to allow as much light into the stone as possible. They do not go through this trouble for fake rubies as they will not be as refractive anyway.

TINY BUBBLE TEST - This is where your loupe is going to come in handy. A real ruby should be nice and clear inside. If you notice any tiny bubbles or streaks inside of the stone than you are looking at a fake or a lab created ruby.

EDGE TEST - A real ruby is cut with nice, clean cut, sharp edges on the stone whereas fakes are nice and smooth.

EMERALDS

These are sort of like rubies in that there are limited tests to tell the difference easily at an auction house but there are a few that will never fail you.

REVERSE RUBY TEST - You may remember that with rubies, if you saw any flaws inside of the stone by using a loupe than you were probably dealing with a fake. Well it is the exact opposite here. Natural emeralds will have streaks, tiny bubbles and imperfections inside of the stone. You might also see black spots inside of very high quality emeralds because of the high amount of carbon in emeralds. You will not see black spots at all in any fake or lab created emeralds.

PAVILLION TEST - Natural emeralds will also have an open back pavillion to allow as much light as possible to shine through the stone. This is not always the case but more often than not this holds true.

ONYX

Onyx is virtually impossible to test without a professional tool (at least this is my experience). There are two pieces of good news here though. Onyx is not overly expensive so there has not been a strong demand for fakes so odds are you will be looking at the real deal.

OPAL

The biggest problem you face here is people using dyes to turn less desireable colors into black opal which is the most commercially desireable. There are really only two tests needed to determine real opals from those that are fake or have been modified.

BUOYANCY TEST - This test is designed to identify the opals that have been dyed. The bad part is that there is no practical way you can do this at the auction house. The process used to dye opals makes them somewhat buoyant so ones that have been dyed and then placed into a pot of water will attempt to float whereas natural, unmodified stones will not.

HEAT TEST - Here is the first test where that lighter and sewing needle will come in handy. If you are confronted with an opal that you are not sure is genuine than heat up the tip of the needle for about 20 seconds and the poke the stone. If the tip of the needle penetrates the stone slightly than you do not have a real opal and the real deal would not be effected by such a test.

AMETHYST - There are two sure fore methods to determine real amethyst in jewelry.

SURFACE COLOR TEST - Natural amethyst will be almost clear in the center while the surface will be colored and shining a light through this stone will create an almost prism effect. Faux stones will be solidly colored and will lack the prism effect.

INTERIOR FLAW TEST - Again you will be using your loupe. A natural amethyst will have at least a few interior bubbles, tiny interior cracks or other imperfections, if the stone lacks these features than it is either fake or lab grown.

PEARL

Pearls are of course not an actual stone but for the purposes of this tutorial I will treat them as such. Pearls are perhaps the most faked mineral in the jewelry business and it can be tricky telling the real from the fake but here are a few to help you out in your travels.

TOOTH TEST - I would not suggest doing this where people can see you which may make this test difficult at time. Natural pearls have a natural gritty feel to them due to the irregularities the layers of nacre (which make up a pearl) contain. A real pearl will feel gritty when rubbed against a tooth whereas a fake one or one cultured in a lab will feel very smmoth against your tooth.

THE BODY HEAT TEST - Pearls are not natural conductors of heat. What you can do is hold a suspect pearl against your cheek for 30 seconds and then remove it and place it on the opposite cheek. If it feels nice and cold than you very well may have a pearl but if it feels close to body temperature than you are not holding a natural pearl.

THE LIGHT TEST - Natural pearls when held under sunlight or a pen light will show different levels of iridescence on each stone due to the variations of the nacre. Simulated pearls will not have this feature and each faux pearl will look the same in bright lighting.

DRILL HOLE TEST - Examine the drill holes on the pearl. Natural pearls are valued by weight so obviously the jeweler wants to preserve as much of that weight as possible. So if it has very tiny holes than it is a good indication it is the real deal whereas if the holes are large than they are more than likely fake. the drill holes on real pearls are also typically drilled from two side leaving both holes of equal size. On fake pearls, the jeweler typically drills straight through leaving one hole slightly bigger than the other. You can also examine the edges of the holes for clues. The edges around the drill holes of real pearls are rarely chipped or flaked whereas fakes chipe and flake easily.

SURFACE LOUPE TEST - By using your loupe you can see the irregularities in the surface of real pearls whereas fakes will look nice and smooth even under a loupe.

WEIGHT TEST - Natural pearls are heavier than the fakes. This is a test that you will have to learn through experience.

VISUAL TEST - Examine the strand the pearls are on. Real pearls typically have small knots in the strand between each pearl whereas you will typically not see this on the fakes. Also examine the settings or the clasp. On real pearls, these will be made of precious metals and not plastic or stainless steel.

Those are the most common precious stones you will encounter on the auction block and now that you know some tricks for that we can move on to the precious metals.

GOLD

There are a few ways to determine real gold without having to resort to very expensive testing methods.

MARK TEST - Gold producers are proud of the fact that they produce it so they mark it. I will delve further into this in the markings section.

SIGHT TEST - Fake gold tends to have a real yellowish shine to it whereas real gold has more of a satin look to it. This is something you will have to learn through experience.

PLATING TEST - Items that are just gold plated will generally be marked as such (more in the marking section) and one way you can tell from antique jewelry is to look for areas of wear.. Use your pen light to shine around the piece and look for any areas that give off a silvery sheen.. If you see that than you have a piece that is only gold plated.

NITRIC ACID TEST - This is another one that you cannot practically perform at the location so you will have to do this at home. Get a bottle of nitric acid (can get it relatively cheap online). Drop a few drops of nitric acid onto the suspect piece. If it is real gold than it will do nothing but fake gold will darken in color.

MAGNET TEST - If a magnet sticks to the piece than it is not gold as gold is non magnetic.

SILVER

Silver is typically pretty easy to test and after awhile you will be able to spot the real from the fake without even having to test but for now here are a few tips to tell the real from the fake.

MARK TEST - Most modern silver (silver since the late 1800's) is clearly marked as such. More on this in the marking section.

WEIGHT TEST - Silver is a very light metal and as such will weigh next to nothing whereas something that is silver plated or just colored silver will have a considerable weight.

MAGNET TEST - If the magnet sticks to the suspected piece than it is not silver as silver is non magnetic.

PLATINUM

You do not see a ton of jewelry (especially antique jewelry) made from platinum but you do see it on occasion. Here are a few ways to tell the real deal from the faux crap.

SIGHT TEST - Platinum (unless altered) will have a silver appearance that borders on being white. If it looks too much like silver than it is not pure platinum.

SCRATCH TEST - Platinum is the most durable of the precious metals so if you see a piece that you suspect is platinum and it has numerous scuffs or scratches than odds are it is not platinum as platinum does not easily scratch.

CORROSION TEST - Platinum is naturally corrosion resistant so if you come across a suspected piece that shows signs of corrosion than it is not real platinum.

WEIGHT TEST - Platinum is roughly twice as heavy as gold. If you suspect a piece is platinum and it is light than it is not true platinum.

COSTUME JEWELRY

I am including a section on this because costume jewelry has taken on a strong market in recent years and in some instances there are pieces of costume jewelry that have a greater value than pieces made from precious metals and stones. Now as far as particular makers, that market changes rapidly and what was popular in the collectors market yesterday may not be today so I would just keep up to date on what is selling (one tip... avon jewelry will never be worth a penny so avoid it). The two areas of costume jewelry that are always valuable and in string demand are pieces made of bakelite and catalin plastic. So bear with me and I will give you a back ground on what these materials are.

BAKELITE
Bakelite was one of the early plastic formulas used in mass production and was invented sometime prior to 1910. It became very popular around ww2 when American forces realized how durable goods made by the Nazis were compared to American war materials. So that knowledge led to a real boom in bakelite production (there was a slight boom in the 30's as well) and soon enough almost everything that could be made of bakelite was.. radios, film projectors, dinnerware and yes, even jewelry. Bakelite jewelry has a very strong collectors market and you can quite often see it coming out of estates. So how do you tell bakelite plastic jewelry from plain old uninteresting plastic jewelry? You can use these tips to help you out:

SOUND TEST - If you tap together two pieces of bakelite they will make a deep thud sound whereas regular plastic will sound much higher pitched when clanged together.

WEIGHT TEST - Bakelite was made from a phenolic resin which is much denser than the resin used to make regular and modern plastics. So the weight of a bakelite piece will be heavier than one made from regular plastic.

HEAT AND SNIFF TEST - You can use two methods here... You can either rub the piece vigorously with your finger or you can hold it close enough to a flame to make it hot yet far enough away not to melt it and then smell it. One of the ingredients in bakelite was formaldehyde which puts off a very distinct smell. You will be able to clearly smell this when bakelite is heated up.

METAL POLISH TEST - Take a soft cloth and smear some metal polish (I suggest simichrome as it seems to work best for this) and rub an inconspicuous area of the suspected bakelite. If it is real bakelite than the cloth will start to turn yellow (This will not be the case with bakelite that is black or was lacquered). Be sure to wash the piece off when you are done.

FORMULA 409 TEST - You can put a small amount of formula 409 on a cotton swab and use the same process as you did with the metal polish. Again, the swab should turn yellow if it is bakelite (again this will not work if the piece is black or was lacquered). be sure to wash the piece when you are done.

SCRATCH TEST - You will use your loupe for this one. Bakelite was durable but prone to scratching (which is one of the reasons for it's downfall as the plastic of choice). Real bakelite will have tiny scratches visible with the use of a loupe.

CATALIN

Catalin plastic is/was a very specific type of plastic that was made the same way as bakelite but with slight formula changes that allowed it be made into a very bright and attractive material. Catalin was very expensive to produce and this items made from catalin were scarce and catalin products are highly sought after by collectors today with some items bringing into the tens of thousands. Catalin jewelry was not really mass produced but you can occasionally find it especially from higher class estates as it was very expensive to acquire. All of the methods used to determine the authenticity of bakelite can apply to catalin except for these additional testing methods:

DENSITY TEST - Catalin was very dense and when it solidified was as hard as brass. Catalin jewelry will be heavy and will feel very thick.

COLOR TEST - Unlike bakelite, catalin was very bright and festive looking. If an item tests as bakelite but is very bright looking than you have found a catalin piece.

Those tests should be able to help you feel more secure in your purchases but t fully feel safe with buying jewelry at auction it helps to have a good understanding of the different marks you might encounter. Some of these you will know but I will include them anyway.

MARKS

Marks can be hard to find on some pieces and you will need your loupe to find the marks on most pieces. On rings, you will usually find the mark inside of the bands though rarely you can find a mark on the pavillion. On necklaces and bracelets you will almost always find the mark on the clasp. On charms you will typicaly find the mark on the back of the charm.

k - You will find a "K" mark on pieces of gold jewelry preceeded by various numbers (10,14,18,22 and 24 being the most common). The "K" stands for Karat which is how you measure the purity of a gold alloy. The higher the number preceeding the "K" the greater the purity (each carat represents 1/24th purity by mass). 24k is the best mark you can hope to see as that represents a 99.9% millesimal fineness. You will not see higher than 24k in jewelry because of the pliability of pure gold. This pliability requires gold jewelry to be mixed with at least a 0.01% base metal formula (usually copper). Bear in mind that some foreign nations (India especially) use a different Karat system than we do and 22k is their version of our 24k so learning styles can be important.

STERLING - Sterling is a mark you will see on silver pieces. Sterling silver is the highest purity marker for silver you will find. Because of how pliable silver is (much more so than gold in pure form) silver 92.5% silver and the rest is base metal (usually copper). The word sterling originated sometime in the 12th century in Europe as a means of identifying pieces that were 92.5% pure silver.

.925 - This is another mark that indicates 92.5% pure silver. Most makers use a mark of "sterling" but some makers prefer to use .925 which means the same thing.

.925/1000 - Yet another mark that says the piece you are looking at it 92.5% pure silver. You do not see this mark on a regular basis.

G.P. - This stands for gold plated. You have to be very careful with gold plated pieces as many times you will see an item marked as if it were real gold and it might appear as "14k" and engraved in very small letters behind it will be the "g.p." mark. Gold plating simply means that the majority of the piece is a base metal (usually copper) and only a very thin layer of gold was used on the surface.

S.P. - This stands for silver plated which means that the mass of the piece is a base metal (usually copper) with only a thin layer of silver on the surface.

P.P. - This stands for Platinum Plated which means the mass of the piece is a base metal (usually copper) with only a very thin layer of platinum on the surface.

E.G.P. - This stand for electro gold plated and simply indicates that the piece is gold plated but was done by electroplating.

E.S.P. - Same as above except the "S" stands for silver

E.P.P. - Same as above except the first "P" stands for platinum.

Platinum - Will be marked on pieces that are at least 95% pure platinum. These marks may also appear as "plat." or "platine".

N.P. - You will occasionally see this on pieces of jewelry and it stands for Nickle Plated which just means this is about the cheapest piece of junk jewelry you will ever find.

COIN - If you see an item stamped "coin" than you have a piece of silver that was produced between the early colonial period in America up until a few years after the American Civil War. In those days, silversmiths were common and it was much cheaper to have a silversmith melt down your silver coins than it was to buy a piece of sterling from Europe. So the silversmiths would melt down the coins and mold the molten silver into items such as pocket watch cases, candle sticks, silverware and jewelry. Many times the silversmith would mark the piece in block letters that said "coin" which stood of course for coin silver. In most instances, coin silver is over 95% pure and in some instances it has a higher silver content than sterling. Sadly, not all pieces were marked with "coin" and were only marked with a makers mark and so you have to really know early american silversmithing, obtain a good knowledge of marks and rely upon other testing methods to determine that it is in fact silver.

MAKERS MARKS

There are literally thousands of companies active today making jewelry not to mention the hundreds of thousands that have done so throughout history so a concise guide on makers marks on this forum are nearly impossible. There are many guides out there which you can purchase that will have a list and illustrations of the most common marks you will find. The good news that most makers since around the end the American Civil War have simplified the marking process and will mark the piece with either the company name, the designer name or a company logo. Prior to that you really have to have some knowledge or a good guide and knowledge will only come with experience. There were thousands upon thousands of marks ranging from the simple crown on up to horses jumping over a fence with a rider holding a spoon. So if anyone finds a piece that they question than just send me an image of it and I will help you identify it.

So I hope that this will help you feel comfortable with buying jewelry at auction and if nothing else, you can enjoy the hunt for valuable pieces for pennies on the dollar.
 
This ^^
There are rumors of high tech saws that will cut the front and back faces off of coins. Then counterfeiters will wrap an alloy with these faces. I don't know if it is true, but I just heard about it.

If you encounter that situation (this works for gems as well and I forgot to mention it in my really long diatribe above) you can take the item in question and brush some rubbing alcohol on it with a q-tip. If the stone or coin has been sliced and fit over a cheaper base metal than the glue that is used in the finishing process with become discolored and will be a dead give away.
 
Thanks, I'll get it done! You guys are so helpful. Yesterday I learned about buying and selling websites and today I learn about auctions...I friggen love this place.

I have found an auction I will be going to tomorrow morning. It will be my first auction ever. I have followed the OP advice and contacted the auctioneer with all of my questions, he too was rather helpful.

The auction listed "Coins: 20 Morgan & Peace Silver Dollars; 6-Barber Coins; Silver & Clad Kennedy Half Dollars; 10-Proof & Mint Sets; 50-Indian Head & 50-Wheat Pennies..." According to coinflation.com the morgan and peace dollars are almost $17 a piece.

Also, I was worried that many people would show up, but it's harvest time in Indiana and this auction is located in the heart of corn/bean country. However, Indiana is waaaayyy ahead of schedule for this years harvest so maybe they will be taking a break and come to the auction. IDK, worst case it's a learning experience.

I'll let you all know how it goes.

Thank you, thank you, thank you to all my friends at the Liberty Forest!!!

Just a bump to find out if you got anything good.
