Is Supreme Kai the Mentor 121 worth grading?

Worth grading — even a PSA 9 beats raw
A Grade 9.5 Supreme Kai the Mentor 121 sells for $220 against $2.99 raw: a $217 spread, 74× the ungraded price. Even a PSA 9 ($200) 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.
