This box trades at $257, 4% below its 1-year high of $267. It's in a steady climb: up 15.1% over 90 days and still rising this week. That puts it in the upper part of its tracked range. It typically swings about ±8.3% in a month — jumpy for a One Piece box, so single-digit dips here are mostly noise. Worst tracked stretch: a 10% drawdown from peak; it sits 4% below that peak now.
eBay supply has held flat over the last 60 days. The set's cards are worth about $7,777 — 30.3× the box price, vs a typical 12.8× for One Piece. That rich multiple adds +1 to the score. Across One Piece boxes the median 30-day move is +1.9% (89% of boxes up), and this one is running 0.5 points behind that pace.
No supply contraction and no price momentum — nothing actionable right now. What to watch for: a 60-day supply drop past 10% while the price holds, which flags BUY SETUP.
