Your next month of grading is free

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.

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.
