Why the verdict weights the odds
Only 16.3% 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 $212.48£159.92€187.12 on average against $171.27£128.91€150.83 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That clears $41.21£31.02€36.29, so grading a clean copy is worth the wait.

What is a PSA 10 Impostor Professor Oak worth?
A PSA 10 Impostor Professor Oak from Base Set (Shadowless) sells for $594.50. 16.3% 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 $594.50£447.45€523.56. 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.
