Worth grading — even a PSA 9 beats raw

A PSA 10 Bob Gibson #320 sells for $5,946 against $33.53 raw: a $5,912 spread, 177× the ungraded price. Even a PSA 9 ($3,326) 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.
