# Espeon #81/90 — Undaunted

## Summary

Espeon Prime is the Undaunted Eeveelution that borrows attacks from its siblings, and it rode that gimmick into real Eeveelution deck builds of the HGSS era. Prime Rares sat at the top of their set, and Espeon is a long-standing fan favorite among Johto starters-turned-icons. The modelled guide sits at $408 with 53 copies traded in 30 days; PSA has slabbed 3,468 of these and only 54 are 10s, a 2% gem rate that makes the raw-to-gem gap the entire trade, and the slabbed population is growing 4% a month, faster than 92% of tracked cards.
