Check any card's price and grade — right on eBay
The CardTrack Chrome extension turns every eBay listing into an instant appraisal: real market value, an AI grade estimate, recent sales and a straight answer — deal or no deal.
Add to Chrome — it's free
Instant price check
Open any eBay card listing and the card's real market value appears automatically — raw and graded, from live sold data. No clicks, no credits.
AI card grading
One click grades the listing photo PSA-style with centering, corners, edges and surface sub-grades — add the back photo for a two-sided grade.
Deal verdict
Asking price vs true market value, converted from £, €, AU$ and C$ automatically. Deal, fair, or above market — answered before you bid.
Mislabel warnings
If the photo shows a different card than the title claims — Base Set vs Base Set 2, wrong number — the extension says so before you pay for the wrong card.
Track & alerts
One click adds any card to your CardTrack watchlist, with price alerts when it lists below market anywhere CardTrack watches.
Every Pokémon printing
English and Japanese, raw and graded — every printing of every Pokémon card in one price guide, so the listing you are looking at is matched to the right one.
The card grading app that lives in your browser
Gem rates, grading ROI, PSA population and the full graded ladder for every card — the numbers that answer "is this worth grading?" before you buy the card, not after.
Frequently asked questions
Is the price checker free?
Yes. Card identification, market values, recent sales and deal verdicts are free and unlimited — no credits used. AI photo grading uses your CardTrack account's monthly credit allowance (free tier included).
Where do the prices come from?
CardTrack blends real completed sales — eBay solds and Fanatics Collect hammer prices — cross-checked against live TCGplayer, Cardmarket and PriceCharting market prices. Updated daily across 20,000+ cards.
How accurate is the AI grade?
It's an estimate from the listing photo (front and optionally back), scored on centering, corners, edges and surface. It's a buying aid, not a substitute for PSA, BGS or CGC.
Does it work on eBay UK?
Yes — eBay.com and eBay.co.uk, with asking prices converted to USD automatically for the comparison.
