This box trades at $506, 30% below its 1-year high of $719. A quiet quarter overall, though it's slipped 3.1% in the last month. That leaves it near the bottom of its tracked range. It typically swings about ±1.9% in a month. Worst tracked stretch: a 30% drawdown from peak; it sits 30% below that peak now.
eBay supply is tightening: active listings are down 21% over the last 60 days (~56 live now). The set's cards are worth about $2,359 — 4.7× 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 1.2 points behind that pace.
Supply is starting to tighten (down 21%) 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.
