I don't think I'd buy silver at a gun show, that sounds like a good way to get fucked over too. People melt old silver coins and sell them as bullion bars ya know, but that's only 90% silver. And pawn shop.....NFW. I usually go to Dave's Gold and Silver Exchange on Broadway, he's a good guy. Any coin shop will do, but that big place on Broadway, Rocky Mountain Coins, they don't impress me too much. They're too big and it looks like they have high overhead to maintain.
