Worth grading — even a PSA 9 beats raw
A PSA 10 Michael Spinks sells for $2,561 against $43.65 raw: a $2,517 spread, 59× the ungraded price. Even a PSA 9 ($410) 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.
