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 is a Rare card, printed in 2000, illustrated by Benimaru Itoh.
It has been out of tournament play for two decades — what is left is collector demand.
