Worth grading — even a PSA 9 beats raw
A Grade 9.5 Don Sutton [So 957] #31 sells for $139 against $19.43 raw: a $120 spread, 7.2× the ungraded price. Even a PSA 9 ($126) 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.
