One Piece Card Game’s OP-17 — The World’s Strongest Warriors — is a month old, the launch-weekend panic pricing has come back to earth, and there’s finally enough secondary-market data to tell what’s actually worth chasing versus what was just hype.
OP-17 released August 28, 2026, as the game’s 4th anniversary expansion, themed around the Elbaf arc and the original Four Emperors. Here’s what’s still holding value a month later, and what’s already cooling off.

1. Luffy SEC-SP (Comic Parallel) — Still the Crown Jewel

The Luffy Secret Rare comic-parallel is the card everyone opened OP-17 hoping to pull, and a month out, it’s holding that reputation. As of early September, the comic-parallel Luffy was asking around ¥1,300,000 on the Japanese secondary market — by far the most expensive card in the set.
Publisher: Bandai Namco
Format: Secret Rare, comic-parallel treatment
Who it’s for: High-end collectors and investors chasing the set’s single biggest chase card.
Why now: If you pulled one, it’s still the headline card of your OP-17 boxes — this is one of the few cards in the set that hasn’t cooled off at all.
2. The Four Emperors Manga Rares
Card Spotlight: The Four Emperors Manga Rares
Whitebeard (OP17-005), Shanks (OP17-022), Kaido (OP17-062), and Big Mom (OP17-112) in their manga-panel parallel treatment. Official sample scans courtesy of Bandai.
The set’s signature gimmick is giving Whitebeard, Shanks, Kaido, and Big Mom the “Manga Rare” (Super Parallel) treatment — full-art versions styled after Eiichiro Oda’s original manga panels instead of standard anime-style card art.
Publisher: Bandai Namco
Format: Manga Rare (Super Parallel), 4th Anniversary exclusives
Who it’s for: Long-term collectors who want the set’s signature anniversary treatment, not just a quick flip.
Why now: These are the cards driving most of OP-17’s anniversary hype, and they’re holding value better than standard chase treatments.
3. Rocks D. Xebec SEC-SP — The Surprise Heavy Hitter
Rocks D. Xebec Secret Rare comic parallel (OP17-118). Official sample scan courtesy of Bandai.
Rocks D. Xebec’s comic-parallel Secret Rare has quietly become the set’s second-most valuable card, asking around ¥511,111 in early September. Xebec isn’t a character most casual fans expected to chase, which makes this one of the better reminders that OP-17’s value isn’t purely tied to name recognition.
Publisher: Bandai Namco
Format: Secret Rare, comic-parallel treatment
Who it’s for: Value-focused collectors who track rarity tier over character popularity.
Why now: This is exactly the kind of card that’s easy to miss on release day and expensive to catch up on later.
4. What’s Already Cooling Off
Base Loki Secret Rare (OP17-119), one of the standard SECs now trading as low as ¥1,300. Official sample scan courtesy of Bandai.
Not everything from OP-17 aged well in a month. Raw card values across the set are down roughly 10% over the last 30 days on average, and sealed booster boxes have softened by about 7%. The Luffy Legendary Rare specifically has dropped around 18% in raw value, and the Manga-Rare Zoro promo lost close to 25% of its raw value in just the last week. Standard Secret Rares outside the parallel treatments — like the base Loki SEC — are trading as low as ¥1,300.
Publisher: Bandai Namco
Format: Standard Secret Rares, non-parallel chase cards
Who it’s for: Anyone deciding what NOT to overpay for right now.
Why now: Launch-weekend boxes were asking ¥15,699–16,000 on the Japanese secondary market — nearly triple MSRP. By September 7, the same sealed boxes had dropped to around ¥12,499 on Mercari. If you’re buying sealed product now instead of chasing singles, you’re paying meaningfully less than launch-weekend buyers did.
There you have it — OP-17 is settling into the pattern most anniversary sets follow: the true chase cards holding value, everything else drifting back to normal. Which card are you still hunting for? Drop it in the comments or subscribe for more bite-sized TCG snacks straight to your inbox.
