Worth grading — even a PSA 9 beats raw

A PSA 10 Johnny McKenzie #6 sells for $331 against $2.37 raw: a $329 spread, 140× the ungraded price. Even a PSA 9 ($84.00) 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.
