Worth grading — even a PSA 9 beats raw

A PSA 10 Willie Mays #300 sells for $17,982 against $105 raw: a $17,877 spread, 171× the ungraded price. Even a PSA 9 ($2,713) 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.
