Why the verdict weights the odds
Only 90.7% 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 $77.33£57.95€67.48 on average against $115.09£86.25€100.43 for the card plus $79.99£59.94€69.80 at Regular, the cheapest level PSA will insure it at. That loses $37.76£28.29€32.95, so a copy is worth more raw.
1 of the 3 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 Koffing (Master Ball Pattern) worth?
A PSA 10 Koffing (Master Ball Pattern) from Japanese Pokemon Card 151 sells for $84.48. 90.7% 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 Koffing (Master Ball Pattern) from Japanese Pokemon Card 151 worth grading?
On the numbers, no. The average submission is worth $77.31 with every grade weighted by how often this card comes back at it, against $15.10 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $37.78.
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 $84.48£63.31€73.72. 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.
