Quick answer
In the One Piece Card Game the same card number can be printed in more than one treatment, and the treatment rather than the number is what separates two objects that look different and cost different amounts. CardSpicy tracks 238 treatments on its One Piece index across three types: 132 SP Cards, 94 Secret Rare parallels and 12 Treasure Rares.
The card number tells you which card it is. It tells you nothing about which printing you are holding.
This is the single most consequential thing to understand about buying One Piece cards, and it is the thing the card number actively hides. A card numbered OP09-015 is one card; it is also several different printed objects, and the difference between them is not a reprint in the ordinary sense, where the same artwork is run again. It is the same number with different artwork, different finish and a different position in the set.
What a treatment is
A treatment is a printing variant that keeps the card number. Bandai’s database records these as suffixes on the number — _p1, _p2 and so on — and every one of them is a distinct entry with its own artwork, even though the base number never changes.
This matters because it means a card number is not an identifier of one object. Searching for a number returns every treatment of that card at once, and sorting by number will not separate them. Two people can both own OP09-015 and own different cards.
The three types we track
| Type | Tracked | Distinct card numbers | What it is |
|---|---|---|---|
| SP Cards | 132 | 123 | A parallel treatment that replaces the artwork entirely, used across boosters, extra boosters and starter decks. The largest tracked tier. |
| Secret Rare parallels | 94 | 40 | A second printing of a Secret Rare with different art, so the same SEC card exists in more than one appearance. |
| Treasure Rares | 12 | 12 | The smallest tier, introduced with OP-17. A distinct rarity rather than a parallel, with very few entries per set. |
The counts are what our index tracks, not what was printed. Bandai does not publish a total for any of these, and a card can be in our index under one treatment while other treatments of the same number exist outside it.
Where the treatments sit, by set
SP treatments are not spread evenly. They cluster in the sets that were given a dedicated parallel programme, and the earliest boosters and the newest ones are lighter than the middle of the run.
| Set prefix | SP treatments tracked |
|---|---|
| OP09 | 19 |
| OP05 | 10 |
| EB03 | 9 |
| OP01 | 7 |
| OP07 | 7 |

That shape is worth reading as a history of the game rather than as a popularity chart. A set with a large number of tracked parallels is a set where Bandai ran an alternate-art programme; a set with few is one where the extra treatments went somewhere else.
How to tell them apart when you are buying
Three things, in order of reliability.
The first is the card number suffix in a listing that gives it, which is the only identifier that is exact. A listing that shows _p2 is unambiguous; a listing that shows only the base number is describing the card, not the object.
The second is the artwork itself, checked against a reference printing. Because a parallel replaces the art rather than tinting it, the two treatments of a card are distinguishable at a glance once you have seen both — but only once you have seen both.
The third is the rarity banner on the card. A parallel treatment usually carries the rarity of the card it parallels, so an SP treatment of a Rare still reads as a Rare; the banner tells you which card it is, not which printing.
What this index covers, and what it does not
Stated plainly. This is a chase-treatment index, not a card-by-card index of the game. It covers the treatments Bandai’s database records with a variant suffix, because those are the ones that can be counted without guessing.
It does not cover every printing that exists. Promotional treatments, tournament prizes and event giveaways are not enumerated in the card database the way booster treatments are, so they are not in these lists. And it does not cover ordinary reprints, where the same number is run again with the same artwork, because those are not a treatment in this sense at all.
What it does give you is the layer where the money and the confusion both sit: the same card number, printed more than one way, counted and listed by the suffix that separates them.
Frequently asked questions
Can two One Piece cards have the same number but different art?
Yes. That is what a treatment is. Bandai records the different printings as suffixes on the same number, so one card number can cover several distinct objects with different artwork.
What is an SP card in One Piece?
SP is a parallel treatment that replaces a card’s artwork entirely. Our index tracks 132 SP treatments across 123 card numbers.
What is a Treasure Rare?
Treasure Rare is the smallest tracked tier, introduced with OP-17. It is a rarity in its own right rather than a parallel, and the database records 12 of them.
Does a Secret Rare have a parallel version?
Often, yes. Our index tracks 94 Secret Rare parallel treatments, meaning the same SEC card number appears in more than one printing with different art.
Are these lists complete?
No, and they are not meant to be read as complete. They cover the treatments Bandai’s card database records with a variant suffix at the date shown. Promotional and event printings sit outside the database and are not included.
