PSA 10 (Gem Mint) is PSA’s top numerical grade. PSA describes it as virtually perfect, with sharp corners, clear focus, original gloss, no staining, and published centering tolerances. The final result is based on PSA’s physical inspection and eye-appeal judgment for the individual card.
PSA publishes grading standards, but the final result follows its physical inspection and eye-appeal judgment for the individual card.

Compare the two standards in our PSA 9 vs PSA 10 guide.
PSA publishes approximately 55/45 or better on the front and 75/25 or better on the reverse. Eye appeal can matter in close cases.
PSA’s published PSA 10 standard calls for four sharp corners. Inspect the actual card carefully rather than relying on a photo alone.
Check edges for wear, chipping, whitening, or roughness. PSA’s result reflects the physical card as a whole, not one measurement alone.
PSA’s standard calls for no staining and full original gloss; it allows a slight printing imperfection only when overall eye appeal is not impaired.
A PSA 10 can carry a different market price from another grade, but there is no universal multiplier. Value depends on the exact card, variation, population, demand, eye appeal, sale timing, and recent comparable sales. A PSA grade is not an appraisal or a promise of resale value.
PSA calls PSA 10 “virtually perfect,” not mechanically perfect. Its published standard permits a limited printing imperfection when overall eye appeal remains strong.
Centering does not need to be exactly 50/50: PSA publishes approximate 55/45 front and 75/25 reverse limits for PSA 10, with judgment reserved for the full card.
A measured ratio or a prior grade does not guarantee a future PSA 10. PSA says grading includes both objective factors and an eye-appeal judgment.
PSA 10 Gem Mint is PSA’s top numerical grade. PSA’s published standard describes a virtually perfect card with sharp corners, strong focus, original gloss, no staining, and approximate centering limits of 55/45 front and 75/25 reverse. PSA makes the final decision after physical review.
There is no reliable single PSA 10 rate across all cards. Print quality, age, handling, card design, and the submitted population vary widely. Review PSA’s population report for the exact card and compare it with the total graded population before drawing conclusions about scarcity.
It depends on the exact card and current market. Compare recent completed sales for the same card, grade, qualifier, and venue. Do not assume a fixed price relationship between PSA 10, BGS 9.5, or any other grade.
Yes. A pack-fresh card can still have centering, printing, surface, corner, or edge issues. Review it carefully under appropriate light before submission; an AI pre-screen can help organize that inspection but does not predict PSA’s result.
Use an AI pre-screen to organize your inspection before a professional submission. It does not determine or guarantee PSA’s final in-hand grade, authenticate a card, or guarantee market value.
