[QUOTE="Clawcoins, post: 3198270, member: 77814"]I also was going to comment that I can make visually coins just like that. You simply put a half, quarter(s), dime(s) or nickel(s) or whatever in a container with a cent, and add muriatic acid to it (Phosphoric Acid as found in Coca Cola can work too for longer periods such as the cup holder in your car). You'll get those inconsistencies dependent upon exposure times of your obverse which was possibly mostly covered by another coin. I have photos of stained coins in other threads, somewhere. The key per Fred in the copy of the article I linked to is the edge should not be the same color as the obv/rev after it's minted and ejected. But it could also be lacquer or gold. You'd have to figure that out.[/QUOTE]
