Why this card matters
pop
83-card 2004 JP set with no reprint pressure, but zero graded pop means unknown ceiling—not proven scarce, just unsubmitted. Supply opacity cuts both ways.
demand
Groudon is a flagship Gen III legendary with enduring collector pull, but JP ex-era demand trails EN crossover appeal. Character is strong; cohort is niche.
artist
Holo ex finish is desirable for the era, but without confirmed artist credit or standout composition data, art premium is assumed, not verified.
catalyst
0% 30d momentum, comp sales at PSA 10 $6 vs raw ask of $435—massive valuation disconnect with no graded pop to justify. No near-term catalyst visible.
