PSA has graded 108 copies. Where they landed:
Why the verdict weights the odds
Only 16.7% 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 $46.09£34.69€40.59 on average against $124.99£94.07€110.07 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That loses $78.90£59.39€69.49, so a copy is worth more raw.

The Unown (O) on this page is the Holofoil printing from EX Unseen Forces, and it trades at $33.36£25.11€29.38 in near mint condition. Only one printing of this card was produced, so there is no cheaper version to confuse it with.
Graded, it runs PSA 7 $13£9.78€11.45, PSA 8 $15.86£11.94€13.97, PSA 9 $39.99£30.10€35.22, CGC/BGS 9.5 $49.99£37.62€44.02, PSA 10 $128.10£96.41€112.81. PSA has graded 108 copies of it. 144 completed sales are on file.
What is a PSA 10 Unown (O) worth?
A PSA 10 Unown (O) from EX Unseen Forces sells for $128.10. 16.7% 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 Unown (O) from EX Unseen Forces worth grading?
On the numbers, no. The average submission is worth $46.09 with every grade weighted by how often this card comes back at it, against $25 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $78.90.
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 $128.10£96.41€112.81. 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.
