This box trades at $524, 27% below its 1-year high of $719. It's down 23.1% over 90 days, but the last week ticked up — possibly finding a floor. That leaves it near the bottom of its tracked range. It typically swings about ±5.2% in a month — jumpy for a One Piece box, so single-digit dips here are mostly noise. Worst tracked stretch: a 28% drawdown from peak; it sits 27% below that peak now.
eBay supply is growing: active listings are up 8% over the last 60 days — more sellers than buyers for now. The set's cards are worth about $2,522 — 4.8× the box price, vs a typical 12.8× for One Piece. That thin multiple trims 1 point off the score. Across One Piece boxes the median 30-day move is +1.9% (89% of boxes up), and this one is running 0.3 points behind that pace.
No supply contraction and no price momentum — nothing actionable right now. What to watch for: a 60-day supply drop past 10% while the price holds, which flags BUY SETUP.
