About Onix in the Pokémon world
A massive snake of boulders. Brock's signature Pokémon in the anime. Base Set Common. Sentimental and cheap.
What is Onix worth?
Onix is a Common, so raw copies trade for very little and most of the print run survives. The only real value is in pristine, high-grade copies, where even a Common can reach low triple digits in 1st Edition PSA 10. See the live price above for the current figure by grade.
Print variants and how to spot them
Confirm the print and finish on Onix before pricing it, since variant and rarity set the market more than the card name alone.
Grading and condition
Onix is the most forgiving tier to grade in the set. Centering on the framed border is the usual cap, and the soft cardstock picks up edge whitening easily, but high print runs keep clean copies affordable.
If you are collecting Onix
Raw copies of Onix are inexpensive enough that grading rarely pays unless you have a clearly pack-fresh example. For set completion, a clean sleeved Onix is the practical move.
