How to check One Piece card prices — and get the right printing

The question everyone with a One Piece binder asks is "what is this worth". The question that has to be answered first is "which card is this". The same character exists as an English printing, a Japanese printing, a base art, an alternate art and a promo, and the gap between them runs to dozens of times. Look up the wrong version and the number means nothing.

Identifying the printing takes under a minute. The code in the lower corner — OP05-119, ST01-006 — gives you the set and the number within it. Our separate guide covers what OP, ST, EB and PRB mean. For the language, read the card itself rather than assuming from the box it came in.

We hold 6,377 One Piece cards: 3,225 English and 3,152 Japanese. The two are priced as separate cards, not one price with a currency conversion, because the two markets genuinely move differently.

The part nobody wants to hear first: most One Piece cards are not expensive. Across the 6,052 cards carrying a market price, the median is THB 42 and 53.8% sit under THB 50. Tip a binder onto a table and half of it is worth less than a coffee.

The other half of that is equally true. 5.6% of the catalog is worth over THB 1,000, and the top tenth starts around THB 269. The question is not whether your pile has value — it is whether you can find the 5.6%.

Where the value sits is more predictable in One Piece than in most games. Sort the catalog by price and almost everything at the top falls into two groups: Japanese promos handed out at events or bundled with merchandise, and alternate arts — full-art SECs, gold-bordered SPs, and the manga-art cards from the PRB sets. Standard-art SRs and Leaders pulled from ordinary boosters usually sit far closer to bulk than people expect.

Monkey.D.Luffy's SEC from OP-11 and the manga-art Roronoa Zoro from PRB-01 make the point. Both are characters everyone knows, but what separates them from the other Luffy and Zoro cards in the same set is the art and the number, not the character. Check the card number before celebrating.

Prices differing between places is normal, not evidence that someone is cheating. A shop price is what a seller wants. A Facebook group price is what someone wants for a fast sale. The market price we show is an average of transactions that actually happened. All three are useful for different things; if you are selling, start from the market price and adjust for condition and how quickly you need the money.

Condition moves the number more than people expect. What we display is the price of a good, ungraded copy. Whitened edges, a bent corner or a scratch across the art all sit below it. Graded copies run on an entirely separate scale, which we store separately and never mix into the raw price.

One Piece prices move faster than the other games we track — sets arrive frequently and the competitive list keeps changing. Our figures update daily, and over 99% of One Piece price rows were refreshed within the last 30 days. Treat a price quoted in an article written last year as a rough landmark, nothing more.

The fastest lookup is the card name plus its number — "Luffy OP05-119" — which searches the English and Japanese printings at once. Pick the one whose code matches your card. If you cannot read the name because it is a Japanese printing, use the camera scanner instead.

With dozens of cards, do not check them one at a time. Pull out the ones that could carry value — full arts, gold borders, manga arts, promos and older Leader cards — and check those first; the rest can be sold as a lot. Our bulk-selling guide covers how to split a pile properly.

Finally, if you check a price intending to sell, the market price is where pricing starts, not what you are guaranteed. Cards people are hunting sell near it; cards with many sellers need to sit under it. That matters more in One Piece than elsewhere, because new supply arrives constantly.
