Steelix

The 2010 Unleashed Steelix is a rare prime Metal-type Pokémon card with 140 HP, evolving from Onix, illustrated by Wataru Kawahara. Raw near-mint copies trade around $124.92, while a PSA 10 is modelled near $299.81 and a PSA 9 near $168.64. In its original set it is a frequent pull — roughly a 1-in-9 booster pull (modelled, not official). Steelix has 12 other printings in the catalogue.
