Against selling raw at $8.64, after the PSA fee for what the slab is worth (a 10 goes in at Standard, $59.99; a 9 at the same level), $25.00 shipping and insurance, and eBay US selling fees, as the selling calculator works them out, with its usual $5 postage and $1 packing on each sale: the same sum as the selling calculator. Each grade is charged the fee level its own slab price needs, so the break-even price carries the fee for a slab at that price, not the PSA 10 fee. These are outcomes if the card gets each grade, not the chance that it will. PSA has graded 501 copies; 246 got a 10.

About this card
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 12th most valuable of the 88 priced cards in Pokémon GO, behind Mewtwo V 72/78 (see the most valuable Pokémon GO cards).
What the data says
The ungraded value has held within 10% over four weeks (−4.8% on 7-day averages), on 82 ungraded sales in 90 days.

PSA has graded 501 copies, 246 of them PSA 10 (49%). That describes the copies sent in, not the chance a given card grades 10.
