# Umbreon #10/90 — Undaunted

## Summary

Umbreon has been a Gen II fan favorite since Gold and Silver, and the Eeveelution popularity never really cools. Mitsuhiro Arita's name carries weight with collectors, and as a holo rare in Undaunted it was a solid mid-tier pull, valued more for affection than tournament play. The modelled guide sits at $34 with 4 copies traded in 30 days, with 333 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.
