Strong grading candidate — 3.7× premium in PSA 10

A PSA 10 Minnie Mouse sells for $807 against $218 raw: a $590 spread, 3.7× the ungraded price. A PSA 9 ($133) sells for less than raw, so anything short of a 10 loses money. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.
