Why the verdict weights the odds
A PSA 10 sells for $436 against $0.41 ungraded plus $79.99 at Regular. Without a PSA population report there is nothing to weight those grades by, so the verdict beside the card speaks in best cases rather than averages. CGC numbers cannot stand in: the prices on this ladder are PSA prices and a CGC 10 is an easier grade to reach.
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.

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 $436. 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.
