This box trades at $866 — 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 ±1.1% in a month — calm by One Piece box standards, so moves that size are worth noticing.
eBay supply is tightening: active listings are down 8% over the last 60 days (~36 live now). The set's cards are worth about $4,130 — 4.8× 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 ahead of that pace.
Supply is starting to tighten (down 8%) 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.
