Is Mockingbird #24 worth grading?

Worth grading — even a PSA 9 beats raw

A Grade 9.5 Mockingbird #24 sells for $33.00 against $1.39 raw: a $31.61 spread, 24× the ungraded price. Even a PSA 9 ($30.00) 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.
