Worth grading — even a PSA 9 beats raw

A Grade 9.5 J. C. Tremblay #178 sells for $95.00 against $2.99 raw: a $92.01 spread, 32× the ungraded price. Even a PSA 9 ($86.11) 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.
