# Riolu (Japanese) #280 — SV4a: Shiny Treasure ex

## Summary

Almost two months before Paldean Fates reached English shelves, Japan had this Shiny Rare Riolu, out in December 2023 in Shiny Treasure ex. The shiny treatment puts the Pokémon's yellow-and-blue palette in a flipped scheme against a sparkling backdrop of gold stars, and the little fighter strikes a light-footed pose. Shiny Rares sit in the chase tier of the Japanese set, and Riolu's popularity among fans lifts it above its slot. The modelled guide sits at $5.19, up 4% over 30 days on 22 copies traded, with 96 days of inventory on the board; a PSA 10 brings $45, 8.7 times raw, but a 83% gem rate against $85 of fees makes grading a losing trade.
