# Gastly #109/165 — Expedition Base Set

## Summary

Gastly was a bulk common in Expedition, the sort of pull that filled out a binder page rather than anchoring a pack. Yukiko Baba is a long-serving Pokémon card illustrator, and the Gen I ghost still carries steady nostalgia among completionists, which is about the demand a common can earn. The modelled guide sits at $6.24, up 1% over 30 days on 99 copies traded, with 1,727 days of inventory sitting on the board; a ACE 10 brings $132, 21 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
