Worth grading — even a PSA 9 beats raw

A PSA 10 Dave Semenko #371 sells for $825 against $10.09 raw: a $815 spread, 82× the ungraded price. Even a PSA 9 ($260) 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.
