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 $86.03. 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.
