# Koffing #74/106 — Great Encounters

## Summary

Koffing is a Gen I Poison gas bag with a cult following, mostly thanks to Team Rocket's Weezing and the "double trouble" gag. In a Diamond & Pearl set it was a common filler Basic, and Lee HyunJung's name is the only real reason to look twice. At a $1.49 modelled guide, with 2 copies traded in 30 days, 87% of this printing’s price is collector premium, since the same card plays for $0.20 out of Journey Together; PSA does not split this card’s population by finish, so no gem rate can be read for it.
