A new shop partner and PSA cert lookup
Our free month of grading runs until September 30, and that's the day we draw the Ohtani. Claim the month before then and you're in. Also inside: our new shop partner in Birmingham, PSA cert lookup, referrals, and five questions worth three free grades.
New shop partner in Birmingham
We've teamed up with 1st Card Collectibles in Birmingham, Alabama. Bring your cards to their shop and pre-grade them on the CHCK app before you decide whether they're worth sending in.

Look up any PSA cert, not just ours
Type in a cert number and you get the grade, the label, the population count and PSA's own front and back images. CHCK certificates are searched at the same time.
Don't have a number? The registry searches every certificate by player, year, set or brand. Sports and Pokémon both.
Buying a slab? Cert numbers are public, and counterfeiters reuse real ones on fake slabs. Always match the images on the cert page to the card in your hand.

Grade your whole collection. Free for a month.
Stop guessing what your cards are worth. Run them through CHCK and get a real condition report back in seconds. Centering, corners, edges and surface, each scored on its own. New and existing users both get the free month.
✅ The measurements, not just a number. Centering, corners, edges and surface each scored on their own, so you can see exactly why the grade came out where it did.
✅ A cert page you can send a buyer. Every grade gets a public report link. Share it instead of arguing about condition in the DMs.
✅ CHCK Bot reads it back to you. Ask it anything about your report: pricing context, condition, what to do with the card next.
