Arbok

The 2014 XY trainer Kit (Noivern) Arbok is a rare Psychic-type Pokémon card with 90 HP, evolving from Ekans. Raw near-mint copies trade around $1.15, while a PSA 10 is modelled near $46.15 and a PSA 9 near $19.15. In its original set it is near-guaranteed — roughly a 1-in-4 booster pull (modelled, not official). Arbok has 12 other printings in the catalogue.
