Worth grading — even a PSA 9 beats raw

A PSA 10 O-Nami sells for $102 against $0.29 raw: a $101 spread, 351× the ungraded price. Even a PSA 9 ($31.86) 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.
