Worth grading — even a PSA 9 beats raw

A PSA 10 Sealeo sells for $813 against $0.71 raw: a $812 spread, 1145× the ungraded price. Even a PSA 9 ($79.73) 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.
