Worth grading — even a PSA 9 beats raw
A PSA 10 Mark McGwire #PP13 sells for $116 against $2.45 raw: a $113 spread, 47× the ungraded price. Even a PSA 9 ($84.83) 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.
