This box trades at $500, 8% below its 1-year high of $542. Price has been broadly stable across the last quarter. That leaves it near the bottom of its tracked range. It typically swings about ±0.3% in a month — calm by One Piece box standards, so moves that size are worth noticing. Worst tracked stretch: a 8% drawdown from peak; it sits 8% below that peak now.
eBay supply is tightening: active listings are down 22% over the last 60 days (~54 live now). The set's cards are worth about $2,947 — 5.9× the box price, vs a typical 18.6× for One Piece. That thin multiple trims 1 point off the score. Across One Piece boxes the median 30-day move is -1.8% (29% of boxes up), and this one is running 1.7 points ahead of that pace.
Tightening supply with a price that's holding is the classic setup — rated Buy. What would end it: supply refilling (the 60-day drop easing back under 10%), or the 30-day price slipping more than 2%.
