Worth grading — even a PSA 9 beats raw

A Grade 9.5 Joe Mauer #231 sells for $38.00 against $6.55 raw: a $31.45 spread, 5.8× the ungraded price. Even a PSA 9 ($34.95) 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.
