# Koga's Koffing #48/132 — Gym Challenge

## Summary

Koga's Koffing is a Gym Challenge uncommon, a mid-tier pull that sat well below the holo chase slots but carries the trainer-owned branding Wizards printed for the Gym sets. Ken Sugimori illustrating gives it an original-artist pedigree, and Koffing has long been a fan-liked Gen I Poison type. The modelled guide sits at $1.95 with 14 copies traded in 30 days; PSA does not split this card’s population by finish, so no gem rate can be read for it, with original packs long past any pull-rate math.
