Magikarp

The 2010 HeartGold SoulSilver Magikarp is a common Water-type Pokémon card with 30 HP, illustrated by Mitsuhiro Arita. Raw near-mint copies trade around $1.86, while a PSA 10 is modelled near $46.86 and a PSA 9 near $19.86. In its original set it is a frequent pull — roughly a 1-in-10 booster pull (modelled, not official). Magikarp has 12 other printings in the catalogue.
