Worth grading — even a PSA 9 beats raw
A PSA 10 Lefty Grove #19 sells for $117,572 against $300 raw: a $117,272 spread, 392× the ungraded price. Even a PSA 9 ($17,496) 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.
