Pricing & Data Methodology
Updated September 12, 2026
Coverage and card lists
We catalog English Pokémon, Disney Lorcana, One Piece and Riftbound cards. Card data comes from the Pokémon TCG community dataset, Lorcast, Bandai's card list and Riot's gallery. Coverage depends on those sources and may lag announcements or omit regional promos. Special beta material, such as Lorcana Format Coconut, is labeled separately.
Market estimates and listing prices
TCGplayer market estimates arrive through the daily tcgcsv feed. They are estimates for the mapped printing and finish, not a guaranteed sale price or an offer from CardOwners. A low listing price is an asking price and may describe a different condition. CardTrader figures are listing prices in EUR. Currency conversion is approximate; shipping, taxes and seller terms are excluded unless a listing explicitly shows them.
Editions, finishes and totals
Different collector printings, such as Pokémon 1st Edition and Shadowless, have separate pages. Finishes sharing a printing use views of the same page. Set totals sum one primary market estimate for each priced printing, excluding unpriced cards and alternate finish prices. They are not the cost of a master set or one vintage edition. Pokémon parent expansion pages include named galleries and vaults, with separate counts and subtotals.
Graded eBay listings
Graded rows show active fixed-price asking prices from eBay, not completed sales or an appraisal. Titles are checked against the English card's identity, edition and finish, then grouped by grader and grade. Automated matching can still miss seller errors or ambiguous titles. Check the actual card, language, certification, condition and seller before buying. Each card shows its listing-check date; coverage is refreshed on a rotating schedule.
Refreshes and missing information
The daily workflow imports data and rebuilds the site. The date beside prices describes the pricing snapshot, not an editorial verification date or a live inventory guarantee. An empty price means our connected feed has no mapped estimate; it does not prove there have been no sales. Failed secondary-source updates can retain an older snapshot. Announced sets can have official previews before the card feed contains a checklist. Release-source links explain catalog dates and confirmed prerelease dates when available.
Price comparisons
Price rankings and FAQ comparisons describe the available data. A rarity category with fewer card designs does not necessarily have lower pack odds. Price concentration does not establish whether a box is worth opening. Historical prices and asking prices do not predict future value.
Corrections and affiliate links
Report an incorrect card or listing through the contact page, including the CardOwners URL, marketplace listing and the mismatch. Marketplace links may earn us a commission; we do not sell the cards or control sellers' prices and inventory.
