Common questions
What rarity is Brock's Onix #21?
Brock's Onix is a Rare Holo. Gym Heroes contains 34 cards at that rarity out of 132 total.
Does condition change what Brock's Onix is worth?
The prices on this page are for raw, ungraded copies.

Scryda scans the card, reads the exact print and finish, and shows raw alongside graded comps.
