Onix

Onix from Base Set 2 is a common card featuring the iconic rock snake Pokémon that many collectors remember from the early anime series, particularly Brock's signature Pokémon. While Base Set 2 cards maintain moderate collector interest as part of the original Pokémon TCG era, common cards from this set generally have limited demand compared to rare cards. Recent pricing has shown downward pressure with notable volatility in the low-dollar market segment.
