Worth grading — even a PSA 9 beats raw
A Grade 9.5 Bill Mazeroski sells for $1,650 against $39.55 raw: a $1,610 spread, 42× the ungraded price. Even a PSA 9 ($1,500) 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.
