Crushing Hammer (Secret Rare)Grading odds
PSA has graded 450 copies. Where they landed:
Why the verdict weights the odds
Only 47.6% 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 $74.49£56.06€65.60 on average against $110.08£82.85€96.94 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That loses $35.59£26.79€31.34, so a copy is worth more raw.

What is a PSA 10 Dialga GX worth?
A PSA 10 Dialga GX from SM - Ultra Prism sells for $117.50. 48.0% 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.
Is Dialga GX from SM - Ultra Prism worth grading?
On the numbers, no. The average submission is worth $75.12 with every grade weighted by how often this card comes back at it, against $10.09 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $34.96.
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 $117.50£88.44€103.48. 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.
