# Slowbro #52/123 — HeartGold SoulSilver

## Summary

Slowbro is a Kantō original with a devoted following for its sleepy charm, and an Uncommon Stage 1 like this was a mid-tier pull rather than a chase slot. Kizuki's name on the illustration credit adds a small draw, though demand stays modest and nostalgia-driven. The modelled guide sits at $5.25, down 19% over 30 days on 11 copies traded, with 333 days of inventory on the board; a PSA 10 guides at $84, 16 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
