# Iron Boulder #071/142 — Stellar Crown

## Summary

Iron Boulder is a Paradox Pokémon, a Gen IX oddity fans treat as a sci-fi Terrakion, and Scarlet & Violet players know its Psychic-and-Colorless attack for hitting hard when hand sizes are matched. GIDORA draws a steady, modest following, and a plain Rare means a mid-tier pull. A $0.21 modelled guide, up 17% over 30 days on 40 copies traded, says bulk, with 560 days of inventory on the board, and the economics stop there: PSA does not split this card’s population by finish, so no gem rate can be read for it, and the same card plays for $0.12 out of Prismatic Evolutions.
