Worth grading — even a PSA 9 beats raw

A PSA 10 Yao Ming [Blue Refractor] #20 sells for $121 against $18.45 raw: a $102 spread, 6.5× the ungraded price. Even a PSA 9 ($60.00) 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.
