I'm a rare coin dealer, but I specialize in American coins. EBay is terrible for selling anything, to be honest, except for sports cards.

The margin on coins, if you're a reputable dealer, is very slim, unless you're dealing with super high-end stuff, where you can go up or down by a thousand bucks and not bat and I.

Most of my inventory runs in the 20 to $50 range, but I can occasionally sell coins that are worth $100 to $250. Unfortunately, the market's been terrible over the summer. I'm stuck with a bunch of silver coinage that's going to take a while to sell.
