What the panel shows
Which card this is
The listing is matched to one printing in CardTrack's catalogue from the page title — set, number and variant — so a TCGplayer product and its CardTrack page line up.
What it sells for
CardTrack's raw and graded market values from completed sales, the same figures as the card's page, so a marketplace's own asking prices can be judged against real solds.
Recent sales
The last completed sales CardTrack has for that card, with grade and date.
Track it
One click adds the card to your CardTrack watchlist for price alerts, and the panel links straight to the full card page.
The full toolkit — deal verdict against the asking price, mislabel warnings and AI photo grading — runs on eBay. See how it works on eBay.
Marketplace questions
Does it show a deal verdict on TCGplayer?
Not yet. On these sites the extension identifies the card and shows CardTrack's values and recent sales; comparing against the listing's own price and grading the photo are eBay-only today, because those sites render prices and images in ways the extension cannot read reliably.
Does it grade photos on Cardmarket or COMC?
No. AI photo grading works on eBay listings only. The value panel on the other marketplaces uses no credits.
Why TCGplayer prices and CardTrack values differ
TCGplayer shows asking prices and its own market price for a listing; CardTrack's value is built from completed sales across marketplaces, cross-checked against live TCGplayer, Cardmarket and PriceCharting prices. Both are useful; they are not the same number.
Is it free?
Yes. The panel on every supported marketplace is free and unlimited.
