Worth grading — even a PSA 9 beats raw
A PSA 10 Bob Swift #148 sells for $3,778 against $14.44 raw: a $3,763 spread, 262× the ungraded price. Even a PSA 9 ($570) 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.
