The names, then the parallels
1Rocks D. Xebec
A set-defining secret rare and Blue leader. The card collectors mean when they say “the Rocks.” Confirm SEC versus leader versus any SP/manga parallel before you save.
2Loki
The other base-numbered secret rare. Same rule: leader, SEC, and special art are different rows.
Yonko leaders
Six leaders is a lot of cardboard that looks similar in a stack. Color and card type (LEADER vs CHARACTER) are the fastest tell after the set code.
Manga / super-parallel hits
One Piece chase value usually lives in manga rares and colored super parallels, not the base SEC. OP-13’s red manga wave is the cautionary tale: the parallel is the card.
Bandai case distribution & pack economics
Bandai manufactures One Piece English booster boxes in sealed master cases of 12 boxes (288 packs total). Each individual booster box contains 24 packs and guarantees either 2 Secret Rares (SEC) or 1 Secret Rare + 1 Alternate Art (AA) character or leader.
The holy grail **Manga Rare** is an unseeded case hit: historically averaging roughly 1 in every 3 to 4 sealed master cases (1 in 36 to 48 booster boxes / 864–1,152 packs).

English packs are not Japanese packs
Japanese OP packs (6 cards) and English OP packs (12 cards) do not contain the same card volume or hit guarantees. Furthermore, English cards utilize a denser blue core cardstock with deeper microscopic foil stamping, whereas Japanese cards use silver reflective foil layers. If you mix languages in one binder, keep language on the catalog row.
OP-16 The Time of Battle (June 2026) is the previous Paramount War set; its manga admirals (Akainu, Kizaru, Aokiji) belong to a different checklist. Do not file an OP-16 manga into OP-17 because the character matches.
