# Shaymin #15/156 — Ultra Prism

## Summary

Shaymin is a Sinnoh mythical with a loyal following, and its Coax attack, fetching three different Basics for a single energy, earned it a role as a bench-filling engine in its era. Mizue's gentle illustration work adds a quiet draw for collectors. The modelled guide sits at $4.71, flat over 30 days on 24 copies traded, with 241 days of inventory on the board; a CGC 10 brings $6.50, 1.4 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
