# Mareep #38/114 — Steam Siege

## Summary

Mareep is a bulk common, the sort of pull that fills out a Steam Siege binder page without anyone chasing it. Johto's wool-covered Lightning starter keeps a gentle fan following through Ampharos, and Eri Yamaki's name is the only extra draw for completionists. The modelled guide sits at $0.27, up 4% over 30 days on 56 copies traded, with 120 days of inventory on the board; a PSA 10 guides at $30, 112 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
