Worth grading — even a PSA 9 beats raw

A PSA 10 Shaquille O'Neal #4 sells for $5,800 against $700 raw: a $5,100 spread, 8.3× the ungraded price. Even a PSA 9 ($1,438) 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.
