Worth grading — even a PSA 9 beats raw
A Grade 9.5 O.J. Mayo #103 sells for $825 against $2.56 raw: a $822 spread, 322× the ungraded price. Even a PSA 9 ($750) 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.
