# Happiny #52/123 — Mysterious Treasures

## Summary

Happiny is a Gen IV baby Pokémon whose Poke-POWER let it hatch into Chansey straight from hand, a quirky Diamond & Pearl-era trick that never defined a deck. As an uncommon in a mid-sized set, it's a modest pull, and Yuka Morii's name gives collectors a small reason to look. The modelled guide sits at $9.87, flat over 30 days on 34 copies traded, with 121 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.
