# Marshtomp #40/109 — Ruby & Sapphire

## Summary

Marshtomp is the quiet middle of the Hoenn starter line, overshadowed by Mudkip's charm and Swampert's reputation. Mitsuhiro Arita is a revered name among illustrators, and as an uncommon from the Ruby & Sapphire debut it offers an easy, affordable way to own his work. The modelled guide sits at $2.26 with 5 copies traded in 30 days; a PSA 10 guides at $518, 229 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
