Grading odds

CGC has graded 2,321 copies. Where they landed:

CGC 101,62670.1%
CGC 951822.3%
CGC 81536.6%
CGC 7170.7%
CGC 660.3%
Lower10.0%

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 $47.67£35.55€42.64 on average against $103.63£77.27€92.70 for the card plus $79.99£59.65€71.55 at Regular, the cheapest level PSA will insure it at. That loses $55.96£41.73€50.06, so a copy is worth more raw.

What is a PSA 10 Blastoise (Mirror Holofoil) worth?

A PSA 10 Blastoise (Mirror Holofoil) from Japanese TAG TEAM GX: Tag All Stars sells for $52.87. 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 $47.67 with every grade weighted by how often this card comes back at it, against $3.64 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $55.96.

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 $52.87£39.42€47.29. 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.
