Worth grading — even a PSA 9 beats raw

A PSA 10 Bob Borkowski #328 sells for $51,821 against $213 raw: a $51,608 spread, 244× the ungraded price. Even a PSA 9 ($7,755) 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.
