Worth grading — even a PSA 9 beats raw
A Grade 9.5 O.J. Mayo Refractor Autograph #153 sells for $98.00 against $6.53 raw: a $91.47 spread, 15× the ungraded price. Even a PSA 9 ($89.00) 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.
