Steelix

The 2003 Aquapolis Steelix is a rare Metal-type Pokémon card with 100 HP, evolving from Onix, illustrated by Hajime Kusajima. Raw near-mint copies trade around $48.74, while a PSA 10 is modelled near $365.55 and a PSA 9 near $126.72. In its original set it is a tough pull — roughly a 1-in-78 booster pull (modelled, not official). Steelix has 12 other printings in the catalogue.
