Worth grading — even a PSA 9 beats raw

A PSA 9 Serperior sells for $110 against $6.60 raw: a $103 spread, 17× the ungraded price. Even a PSA 9 ($110) clears the raw price after an economy-tier ~$25 fee, so a near-miss still comes out ahead. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.
