Strong grading candidate — 11× premium in PSA 8
A PSA 8 Amoonguss sells for $51.79 against $4.81 raw: a $46.98 spread, 11× the ungraded price. A PSA 9 ($21.00) only about breaks even after fees, so the case rests on gemming. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.
