Desirability profile

Why the card is desirable — collectibility vs competitive use. This is a rating, not a price: the fair value above is set only by real comps.

Collector score63/100

Competitive score20/100

Niche

The thesis — why it may be mispriced

The WINNER Ace — ~$25–45 raw and trending up from ~$15 in May. Ace's exceptional character demand gives it a floor, but a same-number JP promo makes variant-matching essential.

Character: Ace — one of the most emotionally-resonant, collected characters in One Piece.
Value: ~$25–45 raw on eBay sold, up from ~$15 in May.
Variant trap: a separate cheap JP P-103 promo trades ~$2–5 — match the WINNER stamp + full art, not the number.
Cap: recurring prize line — supply keeps entering each season.

Biggest risk: Recurring supply caps upside, and P-103 is a variant-confusion magnet — mispricing against the cheap JP promo is the main trap. Anchor to variant-matched sold comps.
