Why the verdict weights the odds
Only 53.8% 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 $64.21£48.12€56.03 on average against $102.47£76.79€89.42 for the card plus $79.99£59.94€69.80 at Regular, the cheapest level PSA will insure it at. That loses $38.26£28.67€33.38, so a copy is worth more raw.
2 of the 5 grades priced above had no sales at that grade, so the figure is modelled from the grades that did rather than observed.

What is a PSA 10 Professor Elm's Lecture worth?
A PSA 10 Professor Elm's Lecture from Japanese TAG TEAM GX: Tag All Stars sells for $108. 53.8% 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 Elm's Lecture from Japanese TAG TEAM GX: Tag All Stars worth grading?
On the numbers, no. The average submission is worth $64.21 with every grade weighted by how often this card comes back at it, against $2.48 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $38.26.
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 $108£80.93€94.24. 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.
