Porygon

The 2004 FireRed & LeafGreen Porygon is an uncommon Colorless-type Pokémon card with 50 HP, illustrated by Tomoaki Imakuni. Raw near-mint copies trade around $7.53, while a PSA 10 is modelled near $52.53 and a PSA 9 near $25.53. In its original set it is a frequent pull — roughly a 1-in-12 booster pull (modelled, not official). Porygon has 12 other printings in the catalogue.
