Why the verdict weights the odds
Only 66.0% 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 $53.46£40.06€46.65 on average against $100.99£75.68€88.12 for the card plus $79.99£59.94€69.80 at Regular, the cheapest level PSA will insure it at. That loses $47.53£35.62€41.48, 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. 66.0% 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.
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£60.64€70.61. 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.
