# Grimer #50/90 — Undaunted

## Summary

Grimer is a bulk common from the HeartGold SoulSilver years, the sort of pull that fills a binder slot without anyone chasing it. Its Kantō sludge heap has a loyal following among Gen I completionists, and Midori Harada's name draws a small crowd of illustrator collectors. A $0.36 modelled guide, flat over 30 days on 7 copies traded, says bulk, with 98 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.
