This box trades at $324, 5% below its 1-year high of $340. It's up 10.8% over 90 days, though the pace has cooled lately. That puts it in the upper part of its tracked range. It typically swings about ±5.1% in a month — jumpy for a One Piece box, so single-digit dips here are mostly noise. Worst tracked stretch: a 27% drawdown from peak; it sits 5% below that peak now.
eBay supply is growing: active listings are up 24% over the last 60 days — more sellers than buyers for now. The set's cards are worth about $7,771 — 24.0× the box price, vs a typical 18.6× for One Piece. That rich multiple adds +1 to the score. Across One Piece boxes the median 30-day move is -1.8% (29% of boxes up), and this one is running 0.1 points ahead of that pace.
No supply contraction and no price momentum — nothing actionable right now. Two ways it earns a Buy rating: a 60-day supply drop past 10% while the price holds, or a value setup — a price near the bottom of its range that stabilizes while the set's card value stays rich vs the box.
