Worth grading — even a PSA 9 beats raw

A PSA 10 Curt Flood #535 sells for $658 against $5.84 raw: a $652 spread, 113× the ungraded price. Even a PSA 9 ($554) 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.
