PSA has graded 40 copies. Where they landed:
Why the verdict weights the odds
Only 80.0% of copies reach a 10, which is why the top price is the wrong number to plan around. Weighting each grade’s PSA price by these odds, a submission is worth $60.39£45.03€54.02 on average against $103.92£77.49€92.96 for the card plus $79.99£59.65€71.55 at Regular, the cheapest level PSA will insure it at. That loses $43.53£32.46€38.94, so a copy is worth more raw.

What is a PSA 10 Professor's Research -P worth?
A PSA 10 Professor's Research -P from Japanese Sword & Shield Promos sells for $75.37. 80.0% of the copies PSA has graded came back a 10, so that price is the best case rather than the one a submission should expect.
Is Professor's Research -P from Japanese Sword & Shield Promos worth grading?
On the numbers, no. The average submission is worth $60.39 with every grade weighted by how often this card comes back at it, against $3.93 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $43.53.
Condition does most of the work below the surface. A copy with soft corners or a print line off centre trades well under the market price shown here, and a copy clean enough to grade trades well above it, which is why the PSA 10 sits at $75.37£56.20€67.42. Before you value your own copy, look at the corners under a light and check the centring on the back, where most cards give themselves away.
