Why the verdict weights the odds
A PSA 10 sells for $37.08£28.03€33.55 against $0.99£0.75€0.90 ungraded plus $79.99£60.48€72.38 at Regular. Without a PSA population report there is nothing to weight those grades by, so this is a best case rather than an average. CGC numbers cannot stand in: the prices on this ladder are PSA prices and a CGC 10 is an easier grade to reach.
2 of the 4 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 Cloyster on this page is the Reverse Holofoil printing from Generations, and it trades at $0.70£0.53€0.63 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 8 $15.77£11.92€14.27, PSA 9 $17£12.85€15.38, CGC/BGS 9.5 $19£14.37€17.19, PSA 10 $37.08£28.03€33.55. PSA has graded 16 copies of it. 106 completed sales are on file.
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 $37.08£28.03€33.55. 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.
