Horsea

The 2003 Aquapolis Horsea is a common Water-type Pokémon card with 50 HP, illustrated by Atsuko Nishida. Raw near-mint copies trade around $8.10, while a PSA 10 is modelled near $53.10 and a PSA 9 near $26.10. In its original set it is a frequent pull — roughly a 1-in-14 booster pull (modelled, not official). Horsea has 12 other printings in the catalogue.
