Worth grading — even a PSA 9 beats raw
A PSA 10 Dave Cowens #30 sells for $599 against $5.93 raw: a $593 spread, 101× the ungraded price. Even a PSA 9 ($110) 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.
