Sentret

The 2003 Aquapolis Sentret is a common Colorless-type Pokémon card with 50 HP, illustrated by Hizuki Misono. Raw near-mint copies trade around $6.83, while a PSA 10 is modelled near $51.83 and a PSA 9 near $24.83. In its original set it is a frequent pull — roughly a 1-in-14 booster pull (modelled, not official). Sentret has 12 other printings in the catalogue.
