Is it worth grading?

Worth grading — even a PSA 9 beats raw

A PSA 10 Great Ball sells for $312 against $1.46 raw: a $310 spread, 213× the ungraded price. Even a PSA 9 ($41.03) 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.
