Worth grading — even a PSA 9 beats raw
A PSA 10 Seong-Jun Kim [Mojo] #BMA-SK sells for $411 against $82.50 raw: a $328 spread, 5.0× the ungraded price. Even a PSA 9 ($141) 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.
