About CardTrack: Card Grader & Value — Pokémon, MTG, Yu-Gi-Oh & More
Check any trading card's value before you buy. CardTrack shows what a card actually sells for, right where you're shopping, and gives you a straight answer: deal, fair, or above market.
AFFILIATE DISCLOSURE CardTrack participates in the eBay Partner Network, eBay's affiliate program. The Buy, Place Bid and eBay search links shown in the extension's panel use CardTrack's affiliate tag, and qualifying purchases made through them earn CardTrack a commission at no extra cost to you. This is how the extension stays free; the same disclosure is shown inside the extension next to those links.
WHAT IT DOES • Values on search results: every card in your eBay search results gets a small badge showing how its price compares with the market, so you can spot the deals before opening a single listing. • Value check: open a listing to see what the card sells for — raw, PSA 9 and PSA 10 — from real sold data, not asking-price guesses. • Deal verdict: compares the asking price with market value, with other currencies converted for you. • Live auctions: on eBay Live and Whatnot streams, CardTrack follows each lot and shows its value as the bids move. If the seller hasn't named the card, type it in for free or let CardTrack read it from the video. • AI grade estimate: one click, or right-click any card photo, to estimate the grade with centering, corners, edges and surface sub-grades. • Price alerts: track a card in one click and get notified when it's listed below market.
EVERY MAJOR GAME Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece and Disney Lorcana — one price guide for your whole collection.
WHERE IT WORKS eBay listings, eBay search results, eBay Live and Whatnot, plus card listings on other popular marketplaces such as TCGplayer and Cardmarket.
WHO IT'S FOR Collectors checking a card's worth before bidding, resellers hunting underpriced listings, and anyone deciding whether a raw card is worth grading.
Values and deal verdicts are free and need no account. A free CardTrack account (cardtrack.com) adds price alerts, AI grading and reading cards from live video, which use your CardTrack AI credits; a free monthly allowance is included.
Screenshots: add one of an eBay search results page with the badges showing, alongside the existing ones. The first screenshot is the one people see in search, so put it first.
