Worth grading — even a PSA 9 beats raw

A Grade 9.5 Bob Baun #21 sells for $235 against $9.43 raw: a $226 spread, 25× the ungraded price. Even a PSA 9 ($213) 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.
