would they have these kinds of coins at the bank?
I wish....there was a particular Congressman (forget his name) that made a HUGE insane stink about this years ago.
he walked into a bank and demanded gold for his money. Of course, the bank refuse because the gold standard was abolished at that time. Still, he continued because of some factor (maybe because he thought it was unconstitutional? who knows). Anyway, to make a long story short, he bitched and complained so much the bank gave him what he wanted.
This won't happen in today's world.
You'll have to do it via a gold or silver dealer.
I recommend Steve Quayle
www.stevequayle.com he's very reputable and has been in the business for years. Yeah, I know he's a "conspiracy theorist", but he knows what's going on economically, and even has an economist on his show every Friday night. He also doesn't keep records of his customers. At first, this sounds odd, but he's explained it time and time again; if the government ever goes into "take all the gold/silver" mode and starts using the Patriot Act to get records from gold dealers (so they know who does and doesn't have gold/silver), you'll be protected.
I personally recommend investing in silver; it has medicinal values (yes, you heard me), and its worth hasn't caught up with gold yet (I'm not saying the values will be equal, but the ratio isn't what it was). Gold will be good, but right now, silver will get you a little more bang for your buck.
as dspectre pointed out (thank you; you worded it a lot better than me), gold/silver isn't a good idea for trying to make a buck...just keep it as a hedge. It will always have the same relative purchasing power, and it could be used as a currency, in the event there is a total collapse of the economy and the dollar.
That said, don't blow all your money on silver/gold. I'd recommend investing in food/water (freeze dried food...I personally recommend "The Freeze Dry Guy"), and camping/survivalist gear (never know what you'll be up against).
Even then, it's good to have cash on hand; only the globalist elites have any idea when a crash is coming...it could be tomorrow (unlikely), or it could be 10 years from now (very unlikely).
