TCGValuerWhat does PSA 10 mean, and how close to perfect is it?

Updated Oct 5, 2026
PSA 10 means Gem Mint — the top grade on PSA’s ten-point scale, and a grade PSA describes as virtually perfect rather than perfect. Four sharp corners, sharp focus, full original gloss, no staining, and centering within about 55/45 on the front and 75/25 on the reverse.
That gap between “virtually perfect” and “perfect” is the whole subject of this page: what the definition actually allows, the single flaw that separates a 10 from a 9, how often cards reach the top of the scale at all, and what the number does not promise you.
What the Gem Mint definition allows#
| Criterion | What PSA requires for a 10 |
|---|---|
| Corners | Four perfectly sharp corners |
| Focus | Sharp focus on the image |
| Surface | Full original gloss, free of staining |
| Printing | A slight printing imperfection is allowed, if it does not hurt the card’s appeal |
| Centering, front | About 55/45 |
| Centering, back | About 75/25 |
PSA writes “approximately” beside those centering figures and states that a small variance may be permitted at the grader’s sole discretion based on the card’s overall eye appeal. Which is the honest answer to most arguments about a 10: the scale is written, but the last word is a person’s.

PSA 10 vs PSA 9: one flaw apart#
| PSA 10 — Gem Mint | PSA 9 — Mint | |
|---|---|---|
| Flaws allowed | A slight print imperfection only | Exactly one minor flaw |
| Examples of that flaw | — | A very slight wax stain on the reverse, a minor printing imperfection, slightly off-white borders |
| Staining | None | A very slight wax stain on the back is tolerated |
| Front centering | 55/45 | 60/40 |
Five percentage points of centering and one tolerated blemish — that is the entire distance between the two grades, and in sale prices it is usually the largest step on the whole scale. Where every other number sits is on the PSA grading scale.
How often cards reach the top#
PSA does not publish how often it awards a 10. What it does publish, on its own getting-started guide, is the shape of the distribution since 2018:
| Card group | PSA’s published figure |
|---|---|
| Modern trading card games, 2003 onward | About 90% graded PSA 8 or higher |
| Modern sport cards, 1986–2016 | About 80% graded PSA 8 or higher |
| Vintage trading card games, pre-2003 | About 80% graded PSA 7 or higher |
PSA calls all of those approximate and adds that it grades each card individually, without regard to population-level results. Read them as a floor, not as odds: a modern card arriving in good shape rarely falls below an 8, and that tells you nothing about whether yours is one of the tens.
What stops a 10#
Centering, almost always
It is the one criterion with a published number and the one you can measure before you pay. Past 55/45 on the front, the top grade is gone whatever the rest of the card looks like.
Any staining
A PSA 9 may carry a very slight wax stain on the reverse. A 10 may not carry staining at all, which makes the back of a vintage card worth as much attention as the front.
Corners under magnification
Sharp to the eye is not the test. The fraying that costs a card the top grade usually shows up only under a loupe, at the single worst corner.
Lost gloss
Full original gloss is part of the definition, so surface wear from a sleeve, a thumb or an album page rules out a 10 long before it becomes visible as a scratch.
Centering is the one you can check at home in a minute with the centering calculator — measure before you spend a fee, not after. If the card is off centre, PSA may also attach the OC qualifier instead of lowering the number, and the qualifier codes are explained on the scale page.
Of the four things that stop a 10, exactly one can be measured at your kitchen table. Measure it before you pay anyone.
There is no PSA 9.5#
PSA awards half points between PSA 2 and PSA 9, for cards showing high-end qualities within a grade, with a clear focus on centering. Above Mint 9 there is no half step: the next grade is Gem Mint 10. Beckett and CGC both use 9.5 in their own scales, and CGC splits the top grade into Pristine 10 and Gem Mint 10 — the comparison is on PSA vs BGS vs CGC.
What a PSA 10 does not mean#
A grade is a condition verdict, not a price and not an appraisal. What a card in a 10 holder sells for is set by buyers, and the only honest way to find it is completed sales of the same card, same printing, same grade — the method on Pokémon card value.
It also does not mean the submission was worth it. The fee ladder is on PSA grading cost, the arithmetic of whether the expected grade beats that cost is on is it worth grading Pokémon cards, and if you are sending from Britain, add the shipping and customs reality on PSA grading in the UK.

Frequently asked questions
What does PSA 10 mean?
PSA 10 means Gem Mint, the top grade on PSA’s ten-point scale. PSA defines it as a virtually perfect card: four sharp corners, sharp focus, full original gloss and no staining, with centering within about 55/45 on the front and 75/25 on the reverse.
What is the difference between a PSA 10 and a PSA 9?
One flaw. A PSA 9 is allowed a single minor imperfection — a very slight wax stain on the back, a minor printing flaw or slightly off-white borders — and centering to 60/40. A 10 allows only a slight print imperfection that does not hurt eye appeal, and no staining at all.
Is a PSA 10 a perfect card?
No, and PSA does not claim that. The written definition is “virtually perfect”, it permits a slight printing imperfection, and it allows centering a little off true at about 55/45. PSA also notes that a small variance may be allowed at the grader’s discretion based on eye appeal.
How rare is a PSA 10?
PSA does not publish a 10 rate. It does publish that roughly 90% of modern trading card game cards from 2003 onward have graded PSA 8 or higher, and about 80% of pre-2003 cards graded PSA 7 or higher. Both figures are approximate and say nothing about any one card.
Does PSA have a 9.5 grade?
No. PSA gives half points between PSA 2 and PSA 9 for cards with high-end qualities inside a grade, with a clear focus on centering, so an 8.5 exists. Above Mint 9 the next step is Gem Mint 10. Beckett and CGC do use 9.5 in their own scales.
Does a PSA 10 prove the card is genuine?
Grading happens only after authentication, so a numeric grade means PSA judged the card genuine and found no evidence of trimming or recolouring. The certification number on the label is what a buyer checks against PSA’s own records before paying a premium for the holder.
