Grading a raw copy
Is it worth grading Mewtwo-GX for a 10?
A raw copy is worth
$800
Grading it costs about $624 with shipping ($224 if it comes back a 9)
If it comes back a 10
+$5,926
against selling it raw
If it comes back a 9
+$396
against selling it raw
A 9 already pays for itself at today's prices, so grading a clean raw copy is worth it on either grade.
PSA's fee at the level each slab's value goes in at (a 10: Premier, $599.00; a 9: Express, $199.00), $25 shipping both ways, and eBay's selling fees on both sales. Run it with your own numbers.
