This box trades at $481, 21% below its 1-year high of $610. It's up 7.2% over 90 days, though the pace has cooled lately. It sits mid-range for the period tracked. It typically swings about ±21.9% in a month — jumpy for a One Piece box, so single-digit dips here are mostly noise. Worst tracked stretch: a 35% drawdown from peak; it sits 21% below that peak now.
eBay supply is tightening: active listings are down 6% over the last 60 days (~306 live now). The set's cards are worth about $41,142 — 85.6× the box price, vs a typical 17.1× for One Piece. That rich multiple adds +1 to the score. Across One Piece boxes the median 30-day move is -0.0% (45% of boxes up), and this one is running 17.8 points ahead of that pace. Beating its own market adds +1 — the move is this box's, not the tide's.
Supply is starting to tighten (down 6%) but hasn't crossed the 10% buy threshold — rated Watch. It upgrades to a Buy rating if the 60-day supply drop reaches 10% while the price holds.
