Worth grading — even a PSA 9 beats raw
A PSA 10 Greg Maddux #31 sells for $1,000 against $30.00 raw: a $970 spread, 33× the ungraded price. Even a PSA 9 ($155) 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.
