The CGC Cards scale
CGC, long established in comics and coins, began grading trading cards in 2020. Cards are graded from 1 to 10 in half-point steps. At the top, a CGC 10 Gem Mint is the equivalent of a PSA 10, and a CGC Pristine 10 sits above it for a card with no visible flaw under CGC’s standards. Subgrades are available but optional. Older slabs may carry labels from before CGC revised its scale in 2023, including the retired “Perfect 10” designation.
Gem Mint 10 against Pristine 10
| Grade | Meaning | How Assetra treats it |
|---|---|---|
| CGC 10 Gem Mint | A virtually perfect card: the standard 10 | Grade 10 |
| CGC Pristine 10 | A flawless card; the highest grade CGC gives | Its own tier above 10 (shown as 10.5), never merged with a 10 |
The two are different markets. Folding Pristine 10 sales into the CGC 10 average would inflate every CGC 10 estimate, so Assetra keeps them apart in the grade ladder, the estimated value and the market cap.
Against a PSA 10
For most modern cards a CGC 10 sells below a PSA 10 of the same card, reflecting PSA’s larger buyer pool, while a CGC Pristine 10, like a BGS Black Label, is scarce enough to sell above it. The size of each gap is card-specific. Open the card on Assetra and read the CGC column of the grade ladder beside PSA and BGS; the population report shows how many Pristine 10s exist.
