Why this card matters
pop
PSA 10 commands a 12x premium over raw and listings are moderate at 68, but n=5 PSA 10 comps and a wide grader spread (PSA10 $666 vs CGC10 $189) suggest inconsistent grading demand rather than true supply scarcity.
demand
Koga is a recognizable Gym Challenge villain with nostalgic appeal, but he lacks the broad fan-favorite pull of trainers like Misty or Giovanni, keeping demand solid but unremarkable.
artist
Standard Gym Challenge holo illustration with no notable alt-art or uniquely celebrated artist pedigree to drive collector premium beyond the set's baseline.
catalyst
30-day momentum is essentially flat at -0.7% with no identifiable event, reprint news, or trend acting as a near-term price driver.
