A Secret Rare (SEC) is the highest rarity Bandai prints on a One Piece Card Game card. You can identify one by the letters SEC in the card's rarity field and by its card number, which sits at the very end of the set's numbering. A typical main booster set has only two native Secret Rares.

Where SEC Sits Among One Piece Rarities

Bandai's official card list uses a small set of rarity codes. SEC is the highest of them. The codes are labels Bandai assigns, and Bandai doesn't publish an official ranking, but SEC is consistently the scarcest code printed in a set.

Code Name What it means
C Common Most frequent cards in every pack
UC Uncommon Slightly scarcer than commons
R Rare Foil-accented; several per box
SR Super Rare Scarcer foil cards with larger art
L Leader The card your deck is built around
SEC Secret Rare Highest printed rarity; numbered last in the set
TR Treasure Rare A newer code used on very few cards

How to Spot a Secret Rare

Look at the bottom right of the card. The rarity code is printed next to the card number. A Secret Rare shows SEC, and its number is the last in the set's base range. In OP-17 The World's Strongest Warriors, for example, the base set ends with Rocks D. Xebec (OP17-118) and Loki (OP17-119), both Secret Rares.

A small star (★) above the rarity code means the card is a parallel: the same card number and rarity with different artwork and finish. Secret Rares can have parallels, and those versions are scarcer than the standard SEC.

OP-17 example OP-17's official card list shows 45 Common, 30 Uncommon, 26 Rare, 10 Super Rare, 6 Leader and 2 Secret Rare cards in the base set. The product page lists three Secret Rares obtainable in packs, because a comic-parallel version of an earlier Luffy SEC (EB04-061) is also inserted. See our OP-17 set guide for the full set.

How Rare Is a Secret Rare?

Bandai does not publish pull rates for the One Piece Card Game. Community case-opening data suggests a typical Japanese box contains fewer than one Secret Rare on average, so a single box may contain none. If you want a specific Secret Rare, buying the single is the only way to guarantee it. Our guide to booster boxes, promo packs and single cards explains the trade-off.

Secret Rares are not the scarcest cards in a set. Manga Rares and SP cards are inserted far less often, even though Bandai doesn't give them a higher printed code.
