Worth grading — even a PSA 9 beats raw
A PSA 10 Lee Mazzilli #42 sells for $198 against $1.99 raw: a $196 spread, 99× the ungraded price. Even a PSA 9 ($35.86) 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.
