The Birthday Pikachu card from the 2nd Anniversary edition is a notable treasure in the Pokémon trading card realm, particularly due to its iconic old back design (旧裏面) and its significant release during a pivotal time for the franchise in the late '90s.

Collectors are drawn to this card not only for its nostalgia but also for its pristine, unopened condition, which is critical to value retention in the competitive market.

Given the rise in demand for early Pokémon cards, particularly original designs, this piece commands a high bid reflective of its rarity among domestic Japanese collectors.

With Pokémon's enduring popularity, particularly for characters like Pikachu, this card exemplifies the lasting appeal and investment potential of vintage collectibles originating from Japan.
