This box trades at $504, 7% 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 ±0.5% 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 7% below that peak now.
eBay supply is tightening: active listings are down 10% over the last 60 days (~57 live now). The set's cards are worth about $3,060 — 6.1× the box price, vs a typical 17.1× for One Piece. That thin multiple trims 1 point off the score. Across One Piece boxes the median 30-day move is -0.0% (45% of boxes up), and this one is running 0.0 points behind that pace.
Supply is starting to tighten (down 10%) 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.
