# Cloyster #34/149 — Sun & Moon

## Summary

Cloyster is a Gen I Water favorite whose spiked shell and Shellder roots keep Kantō nostalgia buyers interested. In the base Sun & Moon set this was a plain Rare, a mid-tier pull with modest tournament use, so demand comes from fans and Saito's illustrator credit rather than any chase status. A $0.16 modelled guide, up 46% over 30 days on 15 copies traded, says bulk, with 1,269 days of inventory on the board, and the economics stop there: a PSA 10 guides at $24, 147 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
