This box trades at $566, 13% below its 1-year high of $653. It ran up 8.8% over 90 days but has given back 7.3% in the last month. It sits mid-range for the period tracked. It typically swings about ±6.8% in a month — jumpy for a One Piece box, so single-digit dips here are mostly noise. Worst tracked stretch: a 13% drawdown from peak; it sits 13% below that peak now.
eBay supply is growing: active listings are up 18% over the last 60 days — more sellers than buyers for now. The set's cards are worth about $21,980 — 38.8× 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 5.5 points behind that pace. Lagging its own market trims 1 point.
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.
