Worth grading — even a PSA 9 beats raw
A PSA 10 Cliff Koroll #28 sells for $112 against $2.50 raw: a $110 spread, 45× the ungraded price. Even a PSA 9 ($59.00) 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.
