Worth grading — even a PSA 9 beats raw

A Grade 9.5 Serena Williams sells for $2,200 against $24.60 raw: a $2,175 spread, 89× the ungraded price. Even a PSA 9 ($2,000) 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.
