Aggron

The 2007 Mysterious Treasures Aggron is a rare holo Metal-type Pokémon card with 130 HP, evolving from Lairon, illustrated by Kouki Saitou. Raw near-mint copies trade around $16.45, while a PSA 10 is modelled near $123.38 and a PSA 9 near $42.77. In its original set it is a tough pull — roughly a 1-in-51 booster pull (modelled, not official). Aggron has 12 other printings in the catalogue.
