Auction of Champions Auction of Champions is the Bidder's Auction House that Specializes in Autographed memorabilia! Auction of Champions is the bidders auction house.

We offer the industry’s lowest buyer’s premium. Auction of Champions only offers items that are fully authenticated by only the most trusted authenticators (JSA, Beckett, PSA/DNA, Fanatics, Tri-Star, Upper Deck, Steiner Sports, Schwartz Sports, Lojo Sports). We DO NOT offer items with an “auction letter of authenticity” like other auction houses do because the winner of the auction still does not have a fully authenticated item and has to spend more money to have their items authenticated. We also do not offer items with only player holograms, items with missing certificates of authenticity, or items authenticated by an unknown 3rd party authenticator. We offer only 100% authentic autographed memorabilia.
