How to find PSA 10 and graded card comps on eBay
A comp is only useful if it is the same card in the same grade. Most bad comps come from mixing grades, counting lots, or trusting a crossed-out Best Offer price.
1. Search the sold listings
- Sign in to eBay. Since July 2026 eBay only shows sold listings to signed-in users.
- Search the card the way sellers title it: year, set, player or Pokémon, card number, grader and grade. Example: 2023 Charizard ex 199/165 PSA 10.
- Open Filter and turn on Sold Items. eBay shows roughly the last 90 days.
- Sort by Ended recently so the newest sales come first. Card prices move fast; a sale from two months ago can be far off today.
2. Keep grades apart
A search for “PSA 10” still returns PSA 9s, BGS 9.5s and raw copies whose titles mention PSA. Read each title, or exclude the others with a minus sign: Charizard 199/165 PSA 10 -9 -BGS -CGC.
| Grade | What to compare against |
|---|---|
| PSA 10 | Other PSA 10s only. A PSA 10 often sells for several times a PSA 9. |
| BGS 9.5 / SGC 10 / CGC 10 | The same grader and grade. Different graders sell at different prices for the same number. |
| Raw | Raw copies in similar condition. Leave out anything slabbed. |
3. Leave out what misleads
- Best Offer sales. When a seller accepts an offer, eBay shows the original asking price crossed out. The real price was lower and is hidden, so skip those.
- Lots and bundles. “Lot of 3” or “PSA 10 + PSA 9” prices are for several cards.
- Outliers. A $1 shill sale or a mistaken $5,000 sale can drag an average. Use the median, not the average.
4. Check the trend
Compare the median of the last 7 days with the weeks before. If the last week is clearly higher, the card is heating up; if lower, wait before you buy.
