Worth grading — even a PSA 9 beats raw

A PSA 10 Lefty Grove #19 sells for $124,259 against $318 raw: a $123,941 spread, 391× the ungraded price. Even a PSA 9 ($18,491) 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.
