# Professor's Research #122/131 — Prismatic Evolutions

## Summary

Professor's Research is the Supporter that powered nearly every deck of its format, and the Prismatic Evolutions copy is simply another printing of a card players already own by the dozen. Hideki Ishikawa's name adds a little interest, but a plain common keeps this one firmly in bulk. The sold median sits at $0.09, down 63% over 30 days on 158 copies traded, with 252 days of inventory on the board; a PSA 10 guides at $31, 339 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
