Worth grading — even a PSA 9 beats raw

A PSA 10 Lou Brock #520 sells for $4,500 against $16.59 raw: a $4,483 spread, 271× the ungraded price. Even a PSA 9 ($356) 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.
