Worth grading — even a PSA 9 beats raw

A PSA 10 Bob Gibson #150 sells for $36,600 against $4.54 raw: a $36,595 spread, 8062× the ungraded price. Even a PSA 9 ($900) 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.
