PSA vs BGS vs CGC: which grader is best for your cards

The three scales side by side

All three graders score a card from 1 to 10 on centering, corners, edges and surface, but they do not describe the top of the scale the same way, and the differences are where the money is.

PSA has one perfect grade. BGS and CGC each have a grade above their standard 10: Black Label for BGS, Pristine 10 for CGC. Assetra tracks those two as their own tier so a perfect copy is never averaged in with ordinary 10s.

How the market prices a 10 from each

For most modern Pokémon, One Piece and sports cards, a PSA 10 is the benchmark: it has the deepest pool of buyers and sells most often. A BGS 9.5 Gem Mint or a CGC 10 Gem Mint of the same card usually trades below the PSA 10, often closer to a PSA 9. A BGS Black Label or a CGC Pristine 10, which are far rarer, usually sells above the PSA 10, sometimes by a wide margin.

These are tendencies, not rules. Vintage cards, Japanese cards and cards with tiny populations behave differently, and the only honest answer for a specific card is its recorded sales. Every Assetra card page shows the latest sale at each grader and grade in one ladder, with the full ledger beneath it, so the comparison takes a few seconds: open the card, then read across PSA 10, BGS 9.5, BGS 10 and CGC 10.

Population and liquidity

PSA has graded far more trading cards than either rival, so its population reports are the largest and its slabs the easiest to sell. That size cuts both ways: a PSA 10 of a popular modern card can have thousands of copies, while the same card may have a few dozen BGS 10s and a handful of Black Labels. A low population in a less common holder is not automatically a premium, because fewer buyers are looking for it.

Read the population report for your card at each grader alongside the sales. Assetra shows both on the card page, grader by grader.

Choosing a grader

• Resale value and speed of sale: PSA, for almost every modern card.
• A copy you believe is flawless: BGS, where a Black Label can be worth a multiple of a PSA 10 of the same card. The subgrades also tell you exactly why a card missed.
• A perfect copy with a CGC preference: CGC, whose Pristine 10 fills the same role as Black Label.
• Vintage and sports: PSA and BGS both carry long histories; check the comps for the specific card, because the gap between them varies by set.

Whatever you choose, decide from the recorded sales for that card at that grade, not from a general rule. Search the sales ledger for your card, or scan the slab from the home page to land on its page directly.

Crossovers and cracking

A card can be “crossed over” from one grader to another, either in its holder with a minimum grade requested or cracked out and submitted raw. Each new slab adds a line to a population report and the old one is rarely removed, so the published populations overstate how many distinct cards exist at a grade. Keep that in mind when a card looks scarce on paper.
