Worth grading — even a PSA 9 beats raw

A PSA 10 Ash-Greninja-EX sells for $2,450 against $115 raw: a $2,335 spread, 21× the ungraded price. Even a PSA 9 ($1,047) 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.
