Professor's Research is card 84 of 78 in the Pokémon GO price guide, a set released in July 2022 during the Sword & Shield era. Its number runs past the set’s printed 78, which marks it as a secret rare. The artwork is by Yusuke Kozaki. In the checklist it sits after Candela 83/78 and before Spark 85/78.
It is the 11th most valuable of the 88 priced cards in Pokémon GO, behind Mewtwo V 72/78 (see the most valuable Pokémon GO cards). A PSA 10 copy is valued at about 5.0× the ungraded price, and a PSA 9 at $17.50, so condition matters a lot for this card.
