PSA 10 vs PSA 9: what's the difference, and how big is the price gap?
A PSA 10 and a PSA 9 can look the same in a listing photo, yet the 10 often sells for several times as much, and far more on vintage. Here is what separates the grades, and how to check the gap for any card.
The short answer
- PSA 10 (Gem Mint) is a virtually perfect card: four sharp corners, full original gloss, no staining, and centering within about 55/45 on the front and 75/25 on the back.
- PSA 9 (Mint) allows one minor flaw, with centering up to about 60/40 on the front and 90/10 on the back.
- On modern chase cards, a PSA 9 often sells for little more than a raw copy, while a PSA 10 sells for several times a PSA 9.
- On vintage holos the gap is far wider, because few old cards survived in gem condition.
- Prices move. Check recent sold listings for the exact card and grade before you buy.
What PSA 10 Gem Mint means
PSA describes a Gem Mint 10 as "a virtually perfect card". It needs four perfectly sharp corners, sharp focus and full original gloss, and it must be free of staining. A slight printing imperfection is allowed only if it doesn't hurt the card's overall appeal.
Centering is what most buyers check first. For a 10, PSA allows up to about 55/45 on the front and 75/25 on the back.
What PSA 9 Mint means
PSA's Mint 9 allows only one minor flaw, such as a very slight wax stain on the back, a minor printing imperfection or slightly off-white borders. Centering can be up to about 60/40 on the front and 90/10 on the back.
In practice, the difference between a 9 and a 10 is often one slightly soft corner, a faint print line or centering that is a little off. That's why two slabs that look identical in a listing can be priced very differently.
How big is the price gap?
It depends on the card and on how many 10s exist, but the pattern is consistent:
- Modern chase cards: a PSA 9 often sells for little more than a raw copy, and a PSA 10 for several times a PSA 9. The 10 is where most of the premium sits.
- Vintage holos: the gap is far wider. Few old cards survived in gem condition, so a PSA 10 can sell for many times a PSA 9.
- Population matters: a 10 that few copies have earned carries a bigger premium than one with thousands of 10s graded.
To see the gap for a specific card, search eBay for the card name, number and grade, turn on the Sold items filter, and compare PSA 9 and PSA 10 sales side by side. Compare totals with shipping, and look at several recent sales rather than one. PSA's population report shows how many copies of each grade exist.
Which grade makes sense for you?
That depends on why you're buying. This is general information, not investment advice.
- To own the card: on many modern cards a PSA 9 is the value pick. You get an authenticated, protected copy for close to the raw price.
- For the top grade: most of what you pay is for the "10" on the label, so the cert number, the seller and recent sold prices for that exact grade matter even more.
- When comparing listings: compare the total with shipping against recent sales of the same card in the same grade, never against a different grade.
A PSA 10's price also depends on how many 10s exist. PSA's population report shows that count, and it grows as more copies are graded.
How SlabPing handles grades
SlabPing prices every grade on its own. For each card it tracks, PSA 10, PSA 9, CGC 10 and the other grades each get a market price from recent completed sales, refreshed daily. A listing is compared only with the price for its own grade, so a PSA 9 is never measured against PSA 10 sales. An alert goes out when the total with shipping is 20% or more under that price. See every card and grade in the price guide.
Questions people ask
Is a PSA 9 worth buying?
For many modern Pokémon cards a PSA 9 sells close to the raw price, which makes it a value pick if you want a graded copy. Whether a given listing is worth it depends on the card and the price, so compare recent sold prices for that exact grade.
Why is a PSA 10 worth so much more than a PSA 9?
Because 10 is the top grade and fewer copies earn it. On modern chase cards a PSA 10 often sells for several times a PSA 9; on vintage holos the multiple can be far higher.
What centering does a PSA 10 need?
About 55/45 or better on the front and 75/25 or better on the back, according to PSA's grading standards. A PSA 9 allows about 60/40 on the front and 90/10 on the back.
Is a PSA 10 worth more than a CGC 10?
Usually, yes: most buyers pay more for a PSA 10 than a CGC 10 of the same card, although CGC's higher Pristine 10 label can sell for more than a PSA 10. Compare recent sold prices for both before you buy.
