# Marshtomp #41/109 — Ruby & Sapphire

## Summary

Marshtomp is the middle stage of the Hoenn Water starter line, and Mudkip's popularity gives the family a loyal following. Ken Sugimori, the original Pokémon artist, illustrated it, and as a Ruby & Sapphire uncommon it was a mid-tier pull whose appeal is mostly nostalgia. The modelled guide sits at $5.78, up 8% over 30 days on 14 copies traded, with 164 days of inventory on the board; a CGC 10 brings $86, 15 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
