# Blastoise #4/165 — Expedition Base Set

## Summary

Blastoise is a Kantō starter final form and one of the most reliably loved Pokémon, which keeps its holos moving whatever the set. Here it's the Expedition-era Holo Rare, Kimiya Masago's work, a gateway pull that e-Series collectors chase for completeness and as a counterpart to the Base Set original. The sold median sits at $646, up 85% over 30 days on 5 copies traded, with 50 days of inventory on the board; 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.
