Why this card matters

pop

22.5y-old JP set, 83-card pool, no reprint risk. But zero graded pop means no verified scarcity signal—raw supply unknown and unconfirmed.

demand

Regirock is a Gen III legendary with a niche fanbase. ex-era nostalgia is rising but Regirock trails Regice/Registeel in pull; cohort demand is moderate at best.

artist

Holo ex finish on 2004 JP card carries vintage tactile appeal. Art is competent but not a standout composition; finish alone drives modest collector interest.

catalyst

0% 30d momentum, zero graded comps (PSA 10 $1 is a data ghost), no active hype. No measurable catalyst present—conviction is purely speculative here.
