# Koffing #76/236 — Cosmic Eclipse

## Summary

Koffing is a bulk common whose Ability only works alongside Roxie, a niche pairing that kept it a curiosity rather than a staple. Naoyo Kimura illustrated it, and Gen I Poison types still earn it a small, affectionate following among completionists. A $0.20 modelled guide, down 5% over 30 days on 8 copies traded, says bulk, with 970 days of inventory on the board, and the economics stop there: PSA does not split this card’s population by finish, so no gem rate can be read for it, and the same card plays for $0.17 out of Journey Together.
