Worth grading — even a PSA 9 beats raw
A PSA 10 Tom Seaver #350 sells for $3,621 against $5.51 raw: a $3,615 spread, 657× the ungraded price. Even a PSA 9 ($598) 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.
