Worth grading — even a PSA 9 beats raw
A Grade 9.5 Sandy Koufax [Refractor] #R3 sells for $968 against $470 raw: a $498 spread, 2.1× the ungraded price. Even a PSA 9 ($880) 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.
