Worth grading — even a PSA 9 beats raw
A PSA 10 Lou Brock #170 sells for $299 against $2.00 raw: a $297 spread, 149× the ungraded price. Even a PSA 9 ($47.53) 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.
