Worth grading — even a PSA 9 beats raw

A Grade 9.5 Bob Gibson sells for $44.99 against $7.95 raw: a $37.04 spread, 5.7× the ungraded price. Even a PSA 9 ($37.82) 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.
