Why this card matters
pop
92 listings and modest graded sample sizes (n=5 PSA9, n=3 PSA8) suggest limited but not truly thin supply; the PSA10 premium (~10x raw) hints at grade-sensitive scarcity at the top tier only.
demand
Brock is a recognizable Gym Leader but not a top-tier nostalgia magnet like Charizard or Pikachu, and Gym Challenge holos occupy a niche collector segment with moderate, stable interest.
artist
No notable alt-art distinction or celebrated illustrator attribution driving outsized collector desirability beyond standard Gym Challenge holo aesthetics.
catalyst
30-day momentum of 10.6% is positive but unspectacular, and the small comp sample sizes (n=5, n=3) make the trend statistically fragile rather than a confirmed breakout.
