# Koffing #54/109 — Ruby & Sapphire

## Summary

Koffing is a bulk common from the first Ruby & Sapphire set, a filler slot nobody opened packs hoping for. Its draw is Atsuko Nishida, one of the original Pokémon card illustrators, so completionists and artist collectors give a humble Gen I poison-gas ball a modest, steady following. A $0.78 modelled guide, down 3% over 30 days on 2 copies traded, says bulk, with 91 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 $0.20 out of Journey Together.
