Centering
Uneven borders cap a grade before anything else is judged. 60/40 or better is the practical threshold for a top grade.
Section 5
Getting cards graded
Grading is third-party condition certification. A card is authenticated, judged on a numeric scale and sealed in a tamper-evident holder. That turns a subjective description into a fixed, comparable data point — which is what lets a market price it confidently.
Why grade only cards worth grading
Every submission carries a per-card fee plus shipping and insurance both ways, and takes weeks to months. A practical rule: the card's realistic graded value should be at least 5–10x the all-in submission cost, or the grade eats the margin. On a card worth $15 raw, even a perfect grade usually leaves you flat once fees are paid. Grade for scarcity, key rookies, vintage, and anything where the top-grade population is genuinely small.
What condition does to value
Corners
Viewed under magnification. A single soft corner is the most common reason a card drops two grade points.
Edges
Chipping and whitening show most on dark-bordered cards, which is why those sets have far lower top-grade rates.
Surface
Print lines, scratches, dimples and loss of gloss. Holo and chrome surfaces are the least forgiving.
Statistical lift: raw to graded
| Grade tier | Typical multiple | What it means |
|---|---|---|
| Gem mint (10) | 4x – 20x raw | Flawless centering, corners, edges and surface. |
| Mint (9) | 1.5x – 3x raw | One minor flaw; the most common strong outcome. |
| Near mint-mint (8) | 1.1x – 1.6x raw | Often barely covers submission cost on cheap cards. |
| Excellent (6–7) | 0.8x – 1.1x raw | Usually value-neutral or negative on modern cards. |
| Below excellent (1–5) | 0.5x – 0.9x raw | Only worthwhile on scarce vintage or key cards. |
Multiples widen with scarcity: on a key vintage card where only a few percent of copies reach the top tier, gem-grade examples commonly trade at 20–100x an ungraded copy. On high-population modern cards, the same top grade may only add 30–80%. The gap between a 9 and a 10 is where most of the money sits — and it is decided by details invisible in a listing photo.
Grading FAQ
What is card grading?
Card grading is third-party condition certification. A card is authenticated, judged on a numeric scale, and sealed in a tamper-evident holder. This turns a subjective condition description into a fixed, comparable data point that lets a market price it confidently.
When is grading a card worth it?
Grading is worth it when the card's realistic graded value is at least 5–10x the all-in submission cost. That usually means scarce vintage, key rookies, low-population cards, and high-value autographs or relics — not cheap bulk modern cards.
How much does grading increase a card's value?
A gem mint (10) grade can lift a card 4x–20x its raw value; a mint (9) typically adds 1.5x–3x; near mint-mint (8) adds only 1.1x–1.6x and often barely covers the submission cost. The gap between a 9 and a 10 is where most of the money sits.
What condition factors affect a card's grade?
Graders judge four areas: centering (60/40 or better is the practical threshold for a top grade), corners (a single soft corner can drop a card two points), edges (chipping and whitening, worst on dark-bordered sets), and surface (print lines, scratches, dimples and gloss loss, least forgiving on holo and chrome cards).
How long does card grading take?
Grading turnaround is typically weeks to months depending on the service level and company. Plan for the card to be unavailable during that window and factor the time cost into whether the expected lift justifies submission.
