Why this card matters
pop
PSA 9 commands a 6.7x premium over raw, signaling real grade scarcity, but 67 active listings and thin comp samples (n=1 for PSA 9) make the supply picture too murky to call definitively tight.
demand
Gym Heroes has a loyal collector base and Team Rocket nostalgia, but a Trainer stadium card lacks the character-driven pull of a named Pokémon or iconic trainer, capping organic demand.
artist
Gym Heroes holos carry period charm, but this is a functional Trainer layout with no standout illustration or alt-art distinction to drive collector premium on aesthetics alone.
catalyst
17.2% 30-day momentum is notable but rests almost entirely on a single PSA 9 sale at $107, making the signal fragile and highly susceptible to mean reversion on the next comp.
