Why this card matters
pop
PSA 10 commands a 13.5× premium over raw and only 54 listings exist, but n=5 PSA 10 comps is a thin base that inflates perceived scarcity.
demand
Koga's Ditto is a niche Gym Challenge villain card with modest nostalgia pull — no mainstream character magnetism to drive broad collector demand.
artist
The Ditto-as-Koga disguise concept is genuinely clever and visually distinct, giving it above-average illustration intrigue for set completionists.
catalyst
30-day momentum is slightly negative at -2.7% with no identifiable event, reprint scare, or grading surge to act as a near-term price catalyst.
