# Koffing #28/68 — Hidden Fates

## Summary

Koffing is a Hidden Fates common, which in a set built around shiny vaulting and Shiny Vault hunting means it was filler between the pulls people actually opened packs for. Gen I Poison-gas oddballs keep a small following, and Saya Tsuruta's name gives completionists a reason to bother. The modelled guide sits at $0.17, up 113% over 30 days on 124 copies traded, with 1,407 days of inventory sitting on the board; a PSA 10 guides at $32, 187 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
