Why this card matters
pop
324 raw listings signals abundant supply, and while PSA 10 commands a 16x premium over raw, the n=5 PSA 10 sold comps and modest graded volumes suggest moderate rather than genuine scarcity.
demand
Marnie is one of the most beloved Trainer characters in the modern era with strong nostalgia and collector pull, sustaining consistent cross-grade demand.
artist
Standard holo Promo treatment — not an alt-art or full-art illustration — limits the premium artwork desirability that drives speculative collector interest.
catalyst
6.3% 30-day momentum is mildly positive but unremarkable, and the TAG 10 $193 comp at n=1 is too thin a sample to confirm a genuine price dislocation.
