Data sources and pricing

Collected.gg connects the English One Piece card catalogue, market prices and imported tournament decklists. Missing prices mean we do not have a matched observation, not that a card is worth zero.

Card identity

Card details originate from the official Bandai catalogue. Alternate arts and reprints are tracked as separate printings. A shared card number does not mean a shared price. Images are served through our image proxy.

Price freshness

The catalogue receives daily TCGplayer market snapshots through TCGCSV. Selected high-value printings receive an additional JustTCG refresh every six hours. This additional refresh does not cover every card. Both Free and Supporter use the same data.

Values are estimates in USD. They do not include selling fees or shipping, and are not guaranteed sale proceeds. Condition is recorded in your collection, but the market feed does not provide a separate price for every condition. Unpriced copies are excluded from totals and reported separately.

Historical charts

A collection chart applies past prices to the cards you hold now. It does not reconstruct the cards you owned on past dates. Older snapshots may be sampled weekly.

Tournaments and legality

One Piece tournament lists come from One Piece Top Decks. Leader percentages describe the lists we have imported, not every player or event. Block overrides and restrictions are maintained from Bandai announcements; the catalogue sync alone does not update tournament rules.
