Grand Line Prices tracks live market prices for the One Piece Card Game — trending cards, price history charts, set-by-set browsing, and a running log of official tournaments and the current competitive meta. The goal is simple: give collectors and players a fast, honest way to check what a card is actually worth right now, backed by real data rather than guesswork.
Where the data comes from
Prices are pulled daily from JustTCG's market data API and reflect real transaction and listing data aggregated from the secondary market. Figures update once per day — this isn't a live tick-by-tick feed, but it's current enough to spot real trends rather than one-off outliers.
Who's behind this
Grand Line Prices is an independently run, one-person project built by a collector for other collectors. It's not affiliated with, endorsed by, or sponsored by Bandai, Shueisha, Toei Animation, or any official One Piece Card Game publisher. Card names, set names, and artwork references are used only to identify products and their market prices.
Affiliate disclosure
Some links on this site are affiliate links — if you buy something after clicking through, this site may earn a small commission at no extra cost to you. That never affects which cards are shown as trending or how prices are reported; the price data comes from the same source regardless of whether a link is an affiliate link.
