One Piece Trade Calculator
Trading cards at locals? Add each side's cards below to compare their total value at a glance. Every card is priced at the cheapest in-stock store price in your market and currency — tap a value to type your own or pick a specific store's price — so you can trade with confidence.
Work out whether a One Piece trade is fair before you shake on it. Put the cards on each side in, and it values both piles at the cheapest live price we have recorded for each card, in your market and currency, then shows the gap. Tap a price to type your own, or to pick one store's price if the cheapest copy is not the one on the table.
Values move week to week and nobody has them memorised, so a trade at a local game store is easy to get wrong by accident: a Parallel can be worth ten times its standard print, and a stack of Rares can be worth less than the one Super Rare across the table.
The valuation is a market snapshot, not an appraisal: condition, sentiment and how much either of you wants the card are things it cannot see. Rarities explained covers why printings of one card are priced so far apart.

Values start from OP Compare's lowest live store price (tap a price to type your own or pick a store). Each side has its own value % for cash settlement. A guide for fair trades — always agree the final deal yourselves.
