PSA has graded 166 copies. Where they landed:
Why the verdict weights the odds
Only 13.3% 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 $64.13£48.27€56.48 on average against $127.32£95.83€112.13 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That loses $63.19£47.56€55.65, so a copy is worth more raw.

The Onix on this page is the Reverse Holofoil printing from EX FireRed & LeafGreen, and it trades at $22.95£17.27€20.21 in near mint condition. The other 1 printing of the same card sits lower, which is normal: the scarcer print run always carries the premium.
Graded, it runs PSA 7 $14.75£11.10€12.99, PSA 8 $28.65£21.56€25.23, PSA 9 $36.06£27.14€31.76, CGC/BGS 9.5 $42.25£31.80€37.21, PSA 10 $280£210.74€246.59. PSA has graded 166 copies of it. 183 completed sales are on file.
What is a PSA 10 Onix worth?
A PSA 10 Onix from EX FireRed & LeafGreen sells for $280. 13.4% 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 Onix from EX FireRed & LeafGreen worth grading?
On the numbers, no. The average submission is worth $64.28 with every grade weighted by how often this card comes back at it, against $27.33 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $63.04.
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 $280£210.74€246.59. 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.
