Worth grading — even a PSA 9 beats raw

A PSA 10 LeBron James #18 sells for $28,215 against $2,570 raw: a $25,645 spread, 11× the ungraded price. Even a PSA 9 ($23,513) 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.
