Worth grading — even a PSA 9 beats raw
A Grade 9.5 Biz Mackey #27 sells for $1,032 against $65.99 raw: a $966 spread, 16× the ungraded price. Even a PSA 9 ($938) 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.
