Brock's Onix · Gym Heroes, what to know.
About the Brock's Onix card
Numbered 69 of 132 in Gym Heroes, released in August 2000, Brock's Onix is a Common, a Basic Fighting-type carrying 100 HP.
As a Basic Pokémon, Onix needs no prior evolution to put into play, which made it a practical card in the era's decks.
Brock is the Rock-type Gym Leader of Pewter City and Ash's longtime traveling companion. Brock's Onix is part of that themed lineup.
Illustrated by Ken Sugimori. Sugimori is the lead character designer of Pokémon itself, so his card art carries the tight, on-model look that defined how the creatures appear in the games.
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 Brock's Onix worth?
Brock's 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
Gym Heroes shipped in 1st Edition and Unlimited, with no Shadowless print. The trainer-prefix naming runs across the set, and the 1st Edition Brock's Onix carries the Edition 1 stamp and a premium over Unlimited in matching grade.
Grading and condition
Brock's Onix is the most forgiving tier to grade in the set. Centering on the framed border is the usual cap, and the soft Wizards-era cardstock picks up edge whitening easily, but high print runs keep clean copies affordable.
If you are collecting Brock's Onix
Raw copies of Brock's Onix are inexpensive enough that grading rarely pays unless you have a clearly pack-fresh example. For set completion, a clean sleeved Brock's Onix is the practical move.
Three prints, three markets.
Edition 1 stamp under the artwork. Trades above Unlimited in matching grade.
No stamp. The standard, more affordable print.
