PSA has graded 199 copies. Where they landed:
Why the verdict weights the odds
Only 19.6% 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 $375.32£282.48€330.53 on average against $131.40£98.90€115.72 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That clears $243.92£183.58€214.81, so grading a clean copy is worth the wait.

What moves the price of this card
The Cloyster on this page is the Reverse Holofoil printing from EX FireRed & LeafGreen, and it trades at $36.90£27.77€32.50 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 $22.48£16.92€19.80, PSA 8 $50.77£38.21€44.71, PSA 9 $200£150.53€176.13, CGC/BGS 9.5 $220£165.58€193.75, PSA 10 $1,422£1,070€1,252. PSA has graded 199 copies of it. 263 completed sales are on file.
What is a PSA 10 Cloyster worth?
A PSA 10 Cloyster from EX FireRed & LeafGreen sells for $1,422. 17.8% 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 Cloyster from EX FireRed & LeafGreen worth grading?
On the numbers, yes. The average submission is worth $346.78 with every grade weighted by how often this card comes back at it, against $31.41 for a raw copy plus $99.99 to send it through PSA Regular, so it clears $215.38.
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 $1,422£1,070€1,252. 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.
