What Assetra is
Assetra is a market data site for graded trading cards: slabs certified by PSA, BGS (Beckett) and CGC, across Pokémon, One Piece, Magic: The Gathering, Yu-Gi-Oh! and other franchises. It records completed sales from marketplaces and auction houses, matches each one to the exact card and grade, and publishes the result as a page per card, per set and per franchise.
The aim is simple: anyone should be able to see what a graded card has really sold for, how many copies exist at each grade, and how that has changed, without relying on asking prices.
What you will find here
- Card pages: the latest sale at every grade, the record sale, the full sales ledger, the population report and an estimated market cap. Search them from the sales ledger.
- Set pages: every card in a set with its prices, the set’s population and market cap, and the cards moving most. The set rankings order every set by market cap.
- Franchise hubs: record sales and every set for each franchise, from the price hubs.
- Live auctions: lots open for bidding now, each with the current bid beside the last sold price, on the live page.
- The monthly market report: market cap by franchise and set, the biggest auction results and the largest moves, in the market report.
- Guides: plain explanations of grading scales, population reports and pricing, in the guides.
Where the numbers come from
Prices come from completed transactions only: auctions that closed with a winning bid and fixed-price listings that sold. Unsold lots, suspicious sales and spam are left out. Population figures come from the graders’ own reports. A market cap is the population of each grade multiplied by that grade’s estimated value, added together.
The methodology sets out every rule, how fresh each figure is, and where the data falls short.
Tools for collectors
Photograph a slab with the scanner and Assetra reads the label and opens the card’s page with the sales at that grade. With an account you can follow cards and auction lots on a watchlist, be alerted to new sales and closing lots, keep a record of your own collection with its current value, and publish a collection page to share.
Assetra is also a free app for iPhone, on the App Store.
Corrections and contact
A catalogue this size contains mistakes: a sale matched to the wrong printing, a card missing from a set, a figure that looks wrong. If you find one, tell us with the page link, and it goes to a person who can fix it.
