Why the verdict weights the odds
Only 21.0% 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 $231.73£175.20€209.67 on average against $122.20£92.39€110.57 for the card plus $79.99£60.48€72.38 at Regular, the cheapest level PSA will insure it at. That clears $109.53£82.81€99.10, so grading a clean copy is worth the wait.

The Onix on this page is the 1st Edition printing from Base Set (Shadowless), and it trades at $31.35£23.70€28.37 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 5 $24.99£18.89€22.61, PSA 6 $27.68£20.93€25.05, PSA 7 $56£42.34€50.67, PSA 8 $66.50£50.28€60.17, PSA 9 $136.84£103.46€123.81, CGC/BGS 9.5 $151£114.16€136.63, PSA 10 $749.33£566.53€678. PSA has graded 4,158 copies of it. 2,100 completed sales are on file.
What is a PSA 10 Onix worth?
A PSA 10 Onix from Base Set (Shadowless) sells for $749.33. 21.1% 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 Base Set (Shadowless) worth grading?
On the numbers, yes. The average submission is worth $234.19 with every grade weighted by how often this card comes back at it, against $22.21 for a raw copy plus $99.99 to send it through PSA Regular, so it clears $111.99.
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 $749.33£566.53€678. 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.
