The only one I am familiar with is Brighton Tokens and Coins 2423 Monroe Avenue. The only time I have been there, they seemed honest, but did not have much for me. That was also the on one umtrr-author recommended.
Yes, I am familiar with Brighton Coins. Has anybody heard of The Jewelry and Coin Exchange (probably no one, huh)?
I'm the webmaster for the Rochester Numismatic Association. We maintain a listing of area dealers at http://the-rna.com/directory.php . The RNA does not enforce a code of ethics for inclusion in this directory, so I can't can't vouch for all these dealers, but I can say that I'm not aware of any bad reputations. Since I represent the RNA in creating this listing I try to avoid playing favorites, so I don't recommend specific dealers. Hopefully this is helpful.
