Raw cards. AI graded. Authenticated.

THE RAW CARD MARKETPLACE

Contendr is the iOS marketplace built for raw trading cards. Bid or buy with Apple Pay, and your money sits in escrow until the card passes our in-house authentication and ships to you in a sealed case.

NO SLABS. NO GUESSWORK. NO GETTING BURNED.

Every card is AI-graded before it can be listed — centering, corners, edges, and surface measured to the hundredth, not eyeballed to the half-point. Live market prices and real eBay comps on every card, from a catalog of hundreds of thousands — sports and Pokémon. Grade your whole collection for fun; list a card for sale in three taps when you're ready.

BUILT DIFFERENT

AI grading on every listing

Escrow + in-house authentication

Sellers ship to us first. You get paid or you get the card — never a surprise. Funds stay in escrow until the card passes authentication and ships to the buyer in a sealed case.
