Worth grading — even a PSA 9 beats raw
A PSA 10 Shawn Kemp #18 sells for $801 against $29.99 raw: a $771 spread, 27× the ungraded price. Even a PSA 9 ($131) 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.
