One Piece TCG OP-17 Global Release: How to Grade Treasure Rares

Bandai confirmed OP-17 The World's Strongest Warriors for a global simultaneous release on August 26, 2026, ending the old English delay. The set introduces Treasure Rares above Secret Rares and focuses on the Elbaf arc and Yonko. Collectors need a grading strategy for the new highest rarity.

One Piece TCG is making history with OP-17 The World's Strongest Warriors. For the first time, English and Japanese versions will release simultaneously on August 26, 2026. The set is a 4th Anniversary booster with 126+1 card types, 6 leaders, 2 Secret Rares, 6 Special Cards, 1 Treasure Rare and 1 DON!! card. The confirmed leaders include Edward Newgate (Red) and Monkey D. Luffy (Black), with four more expected around the Elbaf and Yonko theme.

What is a Treasure Rare?

Treasure Rare is a new tier reported to sit above Secret Rare in OP-17. While Bandai has not fully detailed the print treatment, the market expects Treasure Rares to be the set's ultimate chase cards. Combined with the new global simultaneous release policy, the first-printing Treasure Rares are likely to carry a significant premium, especially in PSA 10 or BGS 9.5 holders.

Cards to Grade from OP-17

• Treasure Rare — The ultimate chase, regardless of which character it features.
• Secret Rares and Manga parallels — Continuation of the popular Admiral-style chase from OP-16.
• Alt-art leaders — Luffy and Whitebeard leader alts are expected to be highly collectible.
• Special Cards and DON!! — Grade only if gem condition and print runs stay low.

Global Simultaneous Release Impact

Ending the English-Japan gap means price discovery will happen faster and arbitrage opportunities will shrink. Collectors in Miami, New York and Los Angeles are pre-ordering boxes now. The key advantage is grading quickly: the first wave of PSA 10 and BGS 9.5 Treasure Rares will likely set the market ceiling before reprints arrive.

Conclusion

OP-17 is a landmark release for One Piece TCG. Pre-grade your Treasure Rares and chase cards immediately after opening to identify the gem candidates before the market floods with raw copies.
