# Grubbin #18/214 — Unbroken Bonds

## Summary

Grubbin is a bulk common whose real claim to fame is Electrical Signal, a two-card Lightning search that fed the Tag Team Lightning decks of its era. Yuka Morii's name draws a small illustrator-collector following, but the demand here stays modest and nostalgic. At a $0.42 modelled guide, down 9% over 30 days on 48 copies traded, with 519 days of inventory on the board, 86% of this printing’s price is collector premium, since the same card plays for $0.06 out of Stellar Crown; PSA does not split this card’s population by finish, so no gem rate can be read for it.
