Strong grading candidate — 8.2× premium in PSA 10

A PSA 10 Primarina-GX sells for $198 against $24.13 raw: a $174 spread, 8.2× the ungraded price. A PSA 9 ($12.89) 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.
