Is Boom Boom #78 worth grading?

Worth grading — even a PSA 9 beats raw
A Grade 9.5 Boom Boom #78 sells for $98.00 against $4.27 raw: a $93.73 spread, 23× the ungraded price. Even a PSA 9 ($89.00) 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.
