About this card’s market
Asking prices run from $8.66 to $210. A spread that wide says more about individual listings than about the card — the market price above is what copies actually sold for.
It sits 48th of 132 priced cards in Gym Heroes.
It is a Rare Holo card, printed in 2000, illustrated by Benimaru Itoh.
It has been out of tournament play for two decades — what is left is collector demand.
