Worth grading — even a PSA 9 beats raw

A PSA 10 Bob Gibson #24 sells for $12,989 against $105 raw: a $12,884 spread, 123× the ungraded price. Even a PSA 9 ($1,979) 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.
