Worth grading — even a PSA 9 beats raw
A PSA 10 Willie Mays #18 sells for $18,541 against $17.62 raw: a $18,524 spread, 1052× the ungraded price. Even a PSA 9 ($583) 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.
