Worth grading — even a PSA 9 beats raw
A Grade 9.5 Moon Knight #MM21 sells for $42.00 against $7.79 raw: a $34.21 spread, 5.4× the ungraded price. Even a PSA 9 ($37.91) 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.
