Worth grading — even a PSA 9 beats raw

A PSA 10 Bob Gibson #530 sells for $1,073 against $8.26 raw: a $1,065 spread, 130× the ungraded price. Even a PSA 9 ($730) 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.
