Worth grading — even a PSA 9 beats raw

A CGC 10 Bill's Maintenance sells for $44.77 against $0.36 raw: a $44.41 spread, 124× the ungraded price. Even a PSA 9 ($35.03) 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.
