Why this card matters
pop
88 listings and healthy raw supply keep scarcity moderate, though the PSA 10 grade cliff (raw $27 → PSA 10 $437) hints at genuine top-grade thinness — but n=1 PSA 10 sale is too small to confirm.
demand
Brock is a recognizable Gym Heroes character but lacks the iconic nostalgia pull of a Pikachu or base-set staple, and -6.3% 30-day momentum signals softening collector interest.
artist
Standard Gym Heroes holo illustration with no notable alt-art treatment or celebrated artist credit to drive premium desirability.
catalyst
Negative 30-day momentum, thin and fragile PSA 10 comp data (n=1), and no visible event or set reprint driving near-term price action.
