Why this card matters
pop
Only 1 active listing and a massive PSA 10 premium (9x raw) signal thin graded supply, but tiny comp sample sizes (n=3–5) make scarcity hard to confirm with confidence.
demand
Gyarados carries strong nostalgic appeal, but the Oversized promo format is a niche collector subset with limited mainstream demand pull.
artist
Standard GX holo treatment with no notable alt-art or standout illustration credit to drive premium collector desirability.
catalyst
Zero 30-day price momentum and a dormant single listing show no active catalyst or market dislocation driving near-term upside.
