davidcyclebackIf you wants names. For the big national auction houses, MastroNet, Robert Edward Auctions and Lelands are reputable. They require expensive consignments. They each deal in both sport and non-sport. Check out their auction catalogs to review the scope.
On eBay, SCGaynor (Scott Gaynor) is a good guy to consign to. He's very knowledgeable and experienced and has a good audience on eBay.
The exclusion of anyone from this post shouldn't be construed as a slight, as I only included folks I've dealt with. I've never dealt with Heritage, Sportscards Plus,etc.
