Worth grading — even a PSA 9 beats raw
A Grade 9.5 Bill Mazeroski #9 sells for $110 against $15.00 raw: a $95.00 spread, 7.3× the ungraded price. Even a PSA 9 ($99.84) 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.
