Worth grading — even a PSA 9 beats raw

A PSA 9 Serperior sells for $48.33 against $9.02 raw: a $39.31 spread, 5.4× the ungraded price. Even a PSA 9 ($48.33) 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.
