# Professor Juniper #101/114 — Black & White

## Summary

Professor Juniper was the Supporter that powered Unova-era decks, a hand-refresh that rewarded players willing to discard good cards for seven fresh ones. Ken Sugimori's name on a trainer card draws a small collector crowd, though as an uncommon it stayed an easy pull rather than a chase. A $0.31 modelled guide with 2 copies traded in 30 days says bulk, and the economics stop there: PSA does not split this card’s population by finish, so no gem rate can be read for it.
