Worth grading — even a PSA 9 beats raw

A PSA 10 Shellder sells for $49.54 against $4.13 raw: a $45.41 spread, 12× the ungraded price. Even a PSA 9 ($38.00) 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.
