This box trades at $268 — right at its 1-year high. Price has been broadly stable across the last quarter. That puts it in the upper part of its tracked range. It typically swings about ±5.0% 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.
eBay supply is tightening: active listings are down 5% over the last 60 days (~156 live now). The set's cards are worth about $6,876 — 25.7× 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 3.6 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 5%) 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.
