About these prices
13.6% of copies sent to PSA come back a 10. Sold and median are 90 days of PSA sales. The 9.5 is a CGC and BGS grade, so it carries no PSA population.

10Grading odds
CGC has graded 238 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 14.0% 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 $16.64£12.53€14.66 on average against $102.35£77.03€90.14 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That loses $85.71£64.51€75.48, so a copy is worth more raw.
1 of the 5 grades priced above had no sales at that grade, so the figure is modelled from the grades that did rather than observed.

What moves the price of this card
The Grass Energy on this page is the 1st Edition printing from Gym Heroes, and it trades at $1.46£1.10€1.29 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 $9.25£6.96€8.15, PSA 8 $13.75£10.35€12.11, PSA 9 $15£11.29€13.21, CGC/BGS 9.5 $17£12.79€14.97, PSA 10 $38.30£28.83€33.73. PSA has graded 172 copies of it. 156 completed sales are on file.
What is a PSA 10 Grass Energy worth?
A PSA 10 Grass Energy from Gym Heroes sells for $38.30. 13.6% 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 Grass Energy from Gym Heroes worth grading?
On the numbers, no. The average submission is worth $16.65 with every grade weighted by how often this card comes back at it, against $2.36 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $85.70.
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 $38.30£28.83€33.73. 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.
