Why the verdict weights the odds

Only 28.8% 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 $98.31£73.99€86.58 on average against $133.49£100.47€117.56 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That loses $35.18£26.48€30.98, so a copy is worth more raw.

What is a PSA 10 Blacephalon GX (Secret) worth?

A PSA 10 Blacephalon GX (Secret) from SM - Lost Thunder sells for $167.50. 29.3% 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.

Is Blacephalon GX (Secret) from SM - Lost Thunder worth grading?

On the numbers, no. The average submission is worth $98.93 with every grade weighted by how often this card comes back at it, against $33.50 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $34.56.

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 $167.50£126.07€147.51. 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.
