Worth grading — even a PSA 9 beats raw

A Grade 9.5 Billy Williams #439 sells for $591 against $3.25 raw: a $588 spread, 182× the ungraded price. Even a PSA 9 ($538) 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.
