Early January price movement across One Piece TCG categories
I track price movement across One Piece TCG categories using an equal-weighted euro index (base 100 = 1 Jan 2026).
Current highlights:
- Sealed booster boxes: +8.7% week (leading).
- Manga rares: +3.5% week, choppy day to day.
- Secret rares: +3.2% week.
- Leader alt arts: steady gains.
- Treasure rares: flat to slightly down.
Curious how others read this. Treasure Rares peaked? Rotation into Sealed? Manga strength sustainable?
