Why this card matters
pop
93 raw listings signals reasonable supply, and PSA 10 premium (~3.3x raw) is modest; small graded sample sizes (n=3–4) make the premium look cleaner than it may be.
demand
Brock is a recognizable Gen 1 character but Rhyhorn carries limited nostalgia pull as a supporting Pokémon with no breakout competitive or cultural moment driving collector interest.
artist
Gym Heroes holos have period charm but Brock's Rhyhorn features no standout illustration or sought-after artist credit that elevates it above a standard set filler.
catalyst
30-day momentum of just 2.3% is essentially flat, with no identifiable event, reprint threat, or market dislocation providing a near-term price trigger.
