Worth grading — even a PSA 9 beats raw
A Grade 9.5 Bert Blyleven #515 sells for $142 against $27.90 raw: a $114 spread, 5.1× the ungraded price. Even a PSA 9 ($130) 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.
