Why the verdict weights the odds
Only 21.9% 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 $175.32£131.95€154.40 on average against $125.14£94.19€110.21 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That clears $50.18£37.76€44.19, so grading a clean copy is worth the wait.

The Koffing on this page is the 1st Edition printing from Base Set (Shadowless), and it trades at $32.29£24.30€28.44 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 $28.19£21.22€24.83, PSA 6 $32.50£24.46€28.62, PSA 7 $36.46£27.44€32.11, PSA 8 $46.40£34.92€40.86, PSA 9 $80.63£60.69€71.01, CGC/BGS 9.5 $98.25£73.95€86.53, PSA 10 $583.93£439.49€514.25. PSA has graded 3,615 copies of it. 1,644 completed sales are on file.
What is a PSA 10 Koffing worth?
A PSA 10 Koffing from Base Set (Shadowless) sells for $583.93. 23.3% 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 Koffing from Base Set (Shadowless) worth grading?
On the numbers, yes. The average submission is worth $183.17 with every grade weighted by how often this card comes back at it, against $25.15 for a raw copy plus $99.99 to send it through PSA Regular, so it clears $58.03.
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 $583.93£439.49€514.25. 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.
