This Mega Gengar EX card from the High Class Pack series holds significant appeal for Pokémon collectors, as it features one of the franchise's beloved ghost-type Pokémon, which consistently commands interest due to its competitive viability and popularity stemming from the animated series that aired in the late '90s.

Released during a high point in Pokémon's trading card evolution, this EX series not only showcases the intricate artistry synonymous with the Japanese print but also highlights a limited run that enhances its rarity in the collector's market.

Condition is paramount, and as an unopened pack, this card benefits from pristine storage, a critical factor when assessing collectible value in Japan, where authenticity and preservation are prioritized.

Given the current bid of ¥40,000, this piece is positioned within the typical range for high-grade EX cards in Japan, reflecting both its desirability and the continued enthusiasm for Pokémon memorabilia.
