# Blastoise #37/165 — Expedition Base Set

## Summary

Blastoise is a Gen I starter final form, so fans have kept it near the top of Water-type affection since the first games. This Expedition Rare is one of the few non-holo mid-tier pulls in an e-Reader-era set, and Kimiya Masago's name adds quiet interest for illustrator-minded collectors. The modelled guide sits at $92 with 18 copies traded in 30 days; a CGC 10 brings $750, 8.2 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.
