Mewtwo Base Set Holo

One of the original 1999 Base Set holos and the most powerful Pokémon of the first generation — Mewtwo carried real competitive weight before becoming a collector cornerstone. PSA 10 1st Edition copies command $2,000–$5,000 while Unlimited PSA 10s sit at $400–$800. Grade sensitivity is extreme: a PSA 9 vs PSA 10 gap can exceed 5× in value.
