CGC has graded 541 copies. Where they landed:
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 34.8% 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 $64.19£48.31€56.53 on average against $103.99£78.27€91.58 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That loses $39.80£29.95€35.05, so a copy is worth more raw.

What moves the price of this card
The Koga's Grimer on this page is the 1st Edition printing from Gym Challenge, and it trades at $4.47£3.36€3.94 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 $17.51£13.18€15.42, PSA 8 $28.11£21.16€24.76, PSA 9 $36.65£27.58€32.28, CGC/BGS 9.5 $40£30.11€35.23, PSA 10 $122.50£92.20€107.88. PSA has graded 517 copies of it. 525 completed sales are on file.
What is a PSA 10 Koga's Grimer worth?
A PSA 10 Koga's Grimer from Gym Challenge sells for $122.50. 36.0% 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 Koga's Grimer from Gym Challenge worth grading?
On the numbers, no. The average submission is worth $65.71 with every grade weighted by how often this card comes back at it, against $4 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $38.28.
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 $122.50£92.20€107.88. 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.
