# Gyarados #123/123 — HeartGold SoulSilver

## Summary

Gyarados is the payoff for raising a Magikarp, and that Red and Blue memory plus the Johto nostalgia of HeartGold SoulSilver keeps Water-type fans interested. A Holo Rare here was a solid mid-tier pull rather than a chase slot, so demand rides on the Pokémon. The modelled guide sits at $370 with 10 copies traded in 30 days; PSA does not split this card’s population by finish, so no gem rate can be read for it.
