Worth grading — even a PSA 9 beats raw

A Grade 9.5 Lefty Grove sells for $143 against $10.00 raw: a $133 spread, 14× the ungraded price. Even a PSA 9 ($130) 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.
