Porygon

The 2008 Great Encounters Porygon is a common Colorless-type Pokémon card with 50 HP, illustrated by Kent Kanetsuna. Raw near-mint copies trade around $0.45, while a PSA 10 is modelled near $45.45 and a PSA 9 near $18.45. In its original set it is a frequent pull — roughly a 1-in-10 booster pull (modelled, not official). Porygon has 12 other printings in the catalogue.
