Why the verdict weights the odds
Only 64.9% 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 $52.54£38.92€46.64 on average against $100.99£74.81€89.63 for the card plus $79.99£59.25€70.99 at Regular, the cheapest level PSA will insure it at. That loses $48.45£35.89€43, so a copy is worth more raw.

What is a PSA 10 Professor Oak's New Theory worth?
A PSA 10 Professor Oak's New Theory from Japanese HeartGold Collection sells for $80.92. 64.9% 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.
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 $80.92£59.94€71.82. 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.
