One Piece TCG OP-17 & OP-18: Chase Cards, PSA 10 Grails & What's Next
The One Piece Card Game's OP-17 The World's Strongest Warriors hit English retail on August 28, 2026, and the secondary market is already moving fast. With a 24-pack booster box MSRP of $119.76 and sealed cases trading at $200–$300 on eBay within days of release, this is shaping up to be one of the most competitively priced — and most volatile — sets of the year. Meanwhile, OP-18 is confirmed for a November 2026 English release, giving collectors a tight 10-week window to decide how deep to go on OP-17 before the next wave resets demand. Use Mystery Collective Radar to track real-time price shifts on both sets.
OP-17 Chase Card Prices Are Already Spiking
OP-17 introduces a second cycle of SP (Special Parallel) cards centered on the Elbaph arc and the Four Emperors roster — and the market has responded aggressively. According to TCGPlayer's July 2026 price-shift tracker, the Monkey D. Luffy SP from OP-17 shot up over $114 in a single week to reach $1,450, while the Boa Hancock SP climbed $71 to hit $1,407. These figures align with the broader trend of SP-rarity One Piece cards commanding four-figure premiums in PSA 10 slabs.
For context, OP-17 booster boxes were pre-ordered at MSRP $119.76 from distributors but arrived at many local game stores with immediate sell-through. Sealed displays at $299.99 for a full 24-pack case were already circulating on the secondary market before the official street date. Collectors who locked in pre-orders at MSRP are sitting on meaningful margin if they hit even a single mid-tier SP pull. The sealed box itself is tracking at $200–$260 on eBay as of early September, meaning the floor for factory-sealed product has not collapsed — a strong signal of sustained demand.
Pre-release events ran August 22 with a sealed format entry of $30 (6 packs included), giving competitive players early access. The Official Playmat — Flame-Flame Fruit Coliseum Edition — drops September 4 at $43 MSRP and is expected to sell out quickly at flagship retailers.

The PSA 10 Grail Ladder: What's Actually Moving
SNKRDUNK's mid-year 2026 PSA 10 trade rankings paint a clear picture of what serious One Piece collectors are chasing. The top tier is dominated by promotional and event-exclusive Monkey D. Luffy cards — particularly the ST21-014 SR promo (from ONE PIECE magazine Special Feature), which trades at ¥17,000+ (~$115 USD) in PSA 10. The P-110 from ONE PIECE DAY '25 fetches ¥28,880 (~$195 USD), and the coveted Luffy BVB x ONE PIECE Matchday 2025 promo [ST13-003 EN] has crossed ¥150,000 (~$1,015 USD) — a staggering figure for a promotional single that underscores just how deep collector demand runs in this game.
Outside the Luffy-heavy upper tiers, Roronoa Zoro SR [ST21-015] from the Flagship Battle Top 8 souvenir set trades at ¥29,800 (~$200 USD) in PSA 10, making it one of the most coveted non-Luffy grails. Boa Hancock [OP07-038] from 500 Years in the Future sits at ¥11,800 (~$80 USD) PSA 10 — undervalued relative to her OP-17 SP spike and worth watching for arbitrage plays. The Nami Comic Parallel SP [OP01-016] from the Premium Booster is arguably the most dramatic outlier at ¥90,000 (~$610 USD), reflecting how first-edition promotional parallels retain outsized long-term value.
The key lesson from the mid-year rankings: promotional and event cards dramatically outperform booster pulls on the PSA 10 secondary market. If you're grading OP-17 pulls, focus on SP and SEC rarities — standard SRs from mass-print sets rarely justify PSA submission fees unless you're pulling from a confirmed first-edition stamp batch. PSA 10 submissions for OP-17 SPs are hitting 4–6 week turnaround at standard service tiers as of August 2026, so factor that delay into any flip timeline.
