Assumes ~$25/card bulk-rate grading (standard service costs more); ignores turnaround time, sub-9 grades, and shipping. A screen, not a promise.

Corphish (54/97) is a Common. PSA has graded 80 copies to date, so graded supply is measurable and growing.

Of the 80 copies PSA has graded, 3% earned a PSA 10. That's a low gem rate, so flawless copies are genuinely hard to come by. Grade-by-grade population and pop-over-time appear with Riffle premium.
