How PSA 10 Prices Are Set (and Where to Check Them Free)
A PSA 10 price is just the last few sold comps — here's how to read them and where to check any card for free.
Updated 2026 · Gem Gains
Every card in the hobby has a "PSA 10 price," but nobody sets it — it's just the trailing average of what recent PSA 10 copies actually sold for. Once you understand which sales feed that number, you can spot cards that are overpriced, underpriced, and worth grading.
What actually determines a PSA 10 price
Three inputs drive every PSA 10 price you see quoted:
- Recent sold comps. The trailing 30–90 days of eBay and auction-house sales for that exact card in a PSA 10 slab. Not asking prices — actual sold prices.
- PSA population count. How many PSA 10s exist. A card with a pop of 200 will generally price higher than the same card with a pop of 20,000.
- Demand. A rookie having a breakout season, a Hall of Fame induction, or a set becoming iconic — these move prices independent of supply.
Where to check a PSA 10 price for free
Most collectors default to eBay's sold-listings filter, but it's slow and inconsistent for multi-parallel cards. Faster options:
- Gem Gains Card Lookup. Free. Type any card and see raw, PSA 9, and PSA 10 prices side by side, plus the net profit after grading. Open Card Lookup →
- eBay sold listings. Filter by "Sold items" and "Graded → PSA 10." Works, but you have to eyeball the average yourself.
- 130point.com. Aggregates recent eBay + auction sales. Useful cross-check.
Why the "list price" isn't your take-home
A PSA 10 quoted at $200 doesn't mean $200 in your pocket. Marketplace fees run around 13% on eBay, plus shipping. Realistic net is ~85% of the comp. If you're grading to flip, always subtract fees before comparing to the raw cost and grading fee — that's the number that tells you whether the card actually profits.
Use PSA 10 prices to spot grading opportunities
The whole grading game is finding cards where the PSA 10 price is much higher than the raw price after all fees. Gem Gains does the subtraction for every tracked card and ranks them by net profit — no spreadsheets required.
