Why this card matters
pop
51 listings is thin, the PSA 10 raw-to-graded premium is extreme (~29x), but small comp sample sizes (n=5 at most) limit confidence in true scarcity depth.
demand
Porygon carries genuine Gen-1 nostalgia but lacks the iconic character pull of Charizard or Pikachu, keeping demand moderate and collector-base relatively niche.
artist
The 'Cool Porygon' promo has a distinctive, era-specific holo treatment that stands out from base-set peers, but it isn't a celebrated alt-art or signature illustrator piece.
catalyst
30-day momentum is essentially flat at -0.9% with no identifiable event or trend driving near-term price dislocation.
