Worth grading — even a PSA 9 beats raw
A PSA 10 Tom Seaver #390 sells for $50.00 against $1.82 raw: a $48.18 spread, 27× the ungraded price. Even a PSA 9 ($29.00) 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.
