This box trades at $393, 1% below its 1-year high of $397. It's up 15.4% over 90 days, though the pace has cooled lately. That puts it in the upper part of its tracked range. It typically swings about ±3.2% in a month.
eBay supply is growing: active listings are up 3% over the last 60 days — more sellers than buyers for now. The set's cards are worth about $9,757 — 24.8× the box price, vs a typical 17.1× for One Piece. That rich multiple adds +1 to the score. Across One Piece boxes the median 30-day move is -0.0% (45% of boxes up), and this one is running 0.5 points behind that pace.
No supply contraction and no price momentum — nothing actionable right now. Two ways it earns a Buy rating: a 60-day supply drop past 10% while the price holds, or a value setup — a price near the bottom of its range that stabilizes while the set's card value stays rich vs the box.
