# Voltorb #21/108 — Roaring Skies

## Summary

Voltorb is a bulk common from a set whose real excitement lived in its Dragon-type and Mega pulls, so it was never a chase slot. Its pull is the Pokéball-disguised oddity that Gen I fans remember, and Suwama Chiaki is a long-running illustrator with a loyal following. A $0.19 modelled guide, up 12% over 30 days on 2 copies traded, says bulk, with 546 days of inventory on the board, and the economics stop there: a PSA 10 brings $150, 789 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
