Grading

The Card Grading Scale, Explained

What every card grade from 1 to 10 means, what a Gem Mint 10 is, and the four things graders judge — centering, corners, edges, and surface. A plain-English guide.

Trading cards are graded on a 1–10 scale, where 10 is the highest. A 10 (“Gem Mint” or “Pristine”) means a card is essentially flawless; 8–9 is near-mint to mint; the middle grades reflect noticeable wear; and low grades show heavy damage. Graders reach the number by judging four things: centering, corners, edges, and surface.

If you’re new to grading, the numbers can feel mysterious. Here’s what they actually mean — in plain English.

What each grade means (1–10)

PCG grades on the 1–10 scale every collector knows, with half grades at the top end only (9.5 and 8.5 — from 8 down, grades are whole numbers).

GradePCG nameWhat it means
10Gem MintEssentially perfect to the eye — sharp corners, clean surface, strong centering.
9.5Gem MintGem-quality with a single hair’s-width imperfection keeping it from the 10.
9Mint+Excellent, with only the tiniest imperfection under close inspection.
8.5MintMint presentation with one minor flaw under magnification.
8Near Mint–MintVery nice, minor flaws (slight wear or centering).
6–7Excellent / Near MintLight, noticeable wear.
4–5Very Good / GoodClear handling wear, softer corners, surface marks.
2–3Good / FairHeavy wear, creases, or damage.
1PoorMajor damage.

Two designations sit outside the numbers, and they’re industry standard:

  • Authentic (AUTH) — the card is genuine, but it isn’t assigned a numeric grade.
  • Altered (ALT) — the card shows evidence of alteration (trimming, recoloring, surface restoration), so a condition grade wouldn’t be honest.

How PCG turns four scores into one grade

Most graders give you a single number and leave the math a mystery. PCG scores each of the four criteria — centering, corners, edges, and surface — from 0 to 10, then combines them into a final score out of 40 that maps to the grade on the label. A PCG 10 requires a combined 39 or higher — meaning a card can’t hide a weak category behind three strong ones. That’s also why we can show you photo evidence of exactly which category held your card back.

What does a Gem Mint 10 mean?

A 10 is the grade everyone chases: a card that presents as flawless — sharp corners, clean edges, an unblemished surface, and strong centering. Very few cards earn it, which is exactly why so many submitters are disappointed. With PCG, if your card falls short of a 10, we’ll show you the photo evidence of why. What’s a PCG 10? →

What do graders actually look at?

Every grade comes down to four things, often called the four C’s: Centering, Corners, Edges, and Surface. A single soft corner or off-center print can pull a card down a full grade. We break each one down — and how to check your own cards — in our grading decision guide.

Common questions

Frequently asked questions.

It's a 1–10 score of a card's physical condition, based on centering, corners, edges, and surface. Higher is better, with 10 being essentially flawless.

The top grade — a card that presents as perfect to the eye across all four grading criteria. At PCG, each of the four is scored 0–10 and a card must total 39 out of 40 to earn the 10. It's rare, which is why realistic expectations matter.

Yes — at the top of the scale only. PCG issues a 9.5 and an 8.5; from 8 down, every grade is a whole number.

Usually a small flaw in one of the four C's — often centering or a soft corner. PCG shows photo evidence of exactly what held a card below a 10.
