# Chansey #20/115 — Unseen Forces

## Summary

Chansey is a Gen I favorite with a devoted following, partly for its gentle healer reputation and its line into Blissey. In Unseen Forces, a regular Rare sat a tier below the ex chase slots, so demand comes from Yukiko Baba's name and nostalgic Colorless collectors. At a $4.97 modelled guide, up 8% over 30 days on 4 copies traded, with 149 days of inventory on the board, this printing is almost entirely collector premium, since the same card plays for $0.17 out of Twilight Masquerade; PSA does not split this card’s population by finish, so no gem rate can be read for it.
