# Shellder #129/165 — Expedition Base Set

## Summary

Shellder is a Gen I Water Basic with a loyal nostalgic following, and Sumiyoshi Kizuki is a respected name among longtime Pokémon illustrators. As an Expedition common it was bulk in its own day, so demand today comes from completionists chasing a clean set rather than from any chase appeal. The modelled guide sits at $4.38, up 3% over 30 days on 35 copies traded, with 90 days of inventory on the board; a ACE 10 brings $87, 20 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it, with original packs long past any pull-rate math.
