Worth grading — even a PSA 9 beats raw
A Grade 9.5 Carl Yastrzemski [AB 9929] #45 sells for $107 against $6.23 raw: a $101 spread, 17× the ungraded price. Even a PSA 9 ($97.50) 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.
