This box trades at $348 — right at its 1-year high. It's up 12.8% over 90 days, though the pace has cooled lately. That puts it in the upper part of its tracked range. It typically swings about ±2.6% in a month.
eBay supply is growing: active listings are up 50% over the last 60 days — more sellers than buyers for now. The set's cards are worth about $3,824 — 11.0× 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 0.1 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.
