Why this card matters
pop
125 listings and modest raw price suggest decent supply, but the 15x PSA 10 premium over raw hints at meaningful gem-rate scarcity at the top tier.
demand
Kingdra is a fan-favorite dragon-type but lacks the mass-market nostalgia pull of flagship Pokémon, keeping demand moderate and collector interest niche.
artist
Standard SM promo holo treatment with no notable alt-art or standout illustration credit to drive premium collector enthusiasm.
catalyst
12.3% 30-day momentum is positive but the PSA 10 comp rests on only 5 sales and the lone CGC 10 at $149 is a single-data-point outlier, making the signal fragile.
