This.
I just did the math on the junk coins too... it's in my sig.
I think those are the closest to whole OZs you can get with the coins at that small of a level (everything before those numbers is just a tad off).
A lot of people won't buy junk because they say it will be too hard to sell later on... I tend to disagree and by keeping your coins in the 47-94-83 method like I do it makes it easy to calculate the OZs while having the coins.
I go into various PM dealers and always pay in cash, never tell them my name, never leave any kind of paper trail. There's a lot of people that think were quacks for hiding our PM purchases but I think they're quacks for not hiding them (and i'm not the Alex Jones conspiracy type). I've only been buying for a couple months now but I've found dealers are more inclined to bend the cash limit rules a little bit if you're a regular by putting them into two separate transactions and such....
If you want to buy more than the legal limit than I would suggest bouncing from dealer to dealer and clearing them out to the legal limit.
PS- Don't pay attention to where the price goes after you buy and don't consider PMs for short term investing. This is all about the long game.
