8Grading odds
CGC has graded 2,222 copies. Where they landed:
These are CGC grades. The prices above are for PSA slabs, and a CGC 10 is not the same grade as a PSA 10, so read the two as separate markets rather than one.
Why the verdict weights the odds
Only 84.9% 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 $41.55£31.14€36.25 on average against $103.24£77.37€90.09 for the card plus $79.99£59.94€69.80 at Regular, the cheapest level PSA will insure it at. That loses $61.69£46.23€53.83, so a copy is worth more raw.

A PSA 10 Blastoise (Mirror Holofoil) from Japanese TAG TEAM GX: Tag All Stars sells for $46.50. 84.9% 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 Blastoise (Mirror Holofoil) from Japanese TAG TEAM GX: Tag All Stars worth grading?
On the numbers, no. The average submission is worth $41.55 with every grade weighted by how often this card comes back at it, against $3.25 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $61.69.
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 $46.50£34.85€40.58. 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.
