Grading Scale

10-point precision · Sports, TCG & non-sports cards

Every card DSG grades is measured against a detailed 10-point scale — from battle-worn Poor 1 to the most coveted grade in the industry, Flawless Diamond 10. Review the full ladder below, then dive into the dedicated criteria for your card type.

Flawless Diamond 10 Half grades awarded Centering capped at 3 points Authenticity guaranteed
Diamond Service Grading
DSG Gem Mint 10 graded Shohei Ohtani card

One scale, every card

The same 10-point standard governs sports, TCG, and non-sports submissions.

Centering rule

Centering alone can never reduce a card’s grade by more than 3 points.

Half grades

Exceptional cards that just miss the next tier earn a ½-point bump.

The 10-point ladder

Every grade, at a glance

A condensed look at what each grade means. Front-centering specs shown apply to both scales; where sports and non-sports back-centering tolerances differ, both are listed.

10
The pinnacleFlawless Diamond 10

A perfect card. Dead-on centering, zero visible flaws of any kind — the most coveted grade in the industry.

Front 50/50 Back 52/48 or better
10
Pack freshGem Mint 10

Beautiful to the naked eye: four razor-sharp corners, unbroken surface gloss, no stains or visible wear. A faint print spot is tolerated only if it doesn’t detract from the card’s eye appeal.

Front 57/43 or better Back 65/35 sports Back 60/40 non-sports
9
Nearly gemMint 9

Four sharp corners with room for one whisper-light corner touch, or up to two very minor surface or edge flaws — a faint printer’s mark or a tiny border imperfection. Without magnification it reads very close to a gem.

Front 65/35 or better Back 90/10 sports Back 70/30 non-sports
8
Sharp to the eyeNM/Mint 8

Corners look sharp unaided but may show slight wear under magnification — up to two of them. A couple of very slight edge chips, small scratches, or printer’s marks are acceptable, none of them obvious to the naked eye.

Front 70/30 or better Back 90/10 sports Back 75/25 non-sports
7
Light wearNMT 7

Slight corner wear, minor scratching, and some small print spots. Print lines or refractor lines are acceptable, and the cut can be slightly skewed.

Front 75/25 or better Back 90/10
6
Honest wearNM 6

Slight corner fuzzing is evident, a skewed cut may be more apparent, focus or registration can be off, edges may be mildly rough, and the surface may have lost its original luster.

Front 80/20 or better Back 90/10
5
Still presents wellEX 5

Minor corner rounding or fuzzing, rough or chipped edges, and up to one very slight one-sided surface crease. Original luster may be gone and some scratching present, but the card still looks good.

Front 85/15 or better Back 90/10
4
Well lovedVG/EX 4

Slightly rounded corners with noticeable surface wear. Light hairline one-sided creases may show on the front and back, and a small tear (1/8″ or less) or minor surface damage may exist.

Front 85/15 or better Back 90/10
3
Visible historyVG 3

Rounded — but not excessive — corners and stronger creasing. Weaker focus and registration, discoloration, and staining become more noticeable at this grade.

Front 90/10 or better Back not factored
2
Heavy wearGood 2

Typically shows one or more print marks, smudges or stains, multiple two-sided creases, pinholes or small tears, surface scuffing, rounded corners, and ink or pencil marks.

Front 90/10 or better Back not factored
1
Been to battlePoor 1

The lowest grade possible — you can clearly see this card has lived a life. But inside DSG encapsulation, one thing is 100% certain: it’s an authentic card, not a counterfeit. Often graded simply because its owner loves it.

Authenticity guaranteed
½
The bonus pointHalf Grades

Reserved for cards that land solidly in a grade but are exceptionally nice — just barely missing the next tier up. When a card earns it, DSG awards the half point.

Awarded at grader’s discretion
How grades are protected

Two rules worth knowing

The 3-point centering cap

Centering matters, but it can’t sink an otherwise beautiful card. Under DSG standards, centering can reduce a card’s grade by a maximum of 3 points — corners, edges, and surface always get their fair say in the final number.

Why half grades exist

Some cards sit right on the line. When a card is exceptionally nice for its grade and just barely misses the next tier, DSG recognizes it with a half grade — so an outstanding 8 doesn’t get lumped in with an ordinary one.
