Worth grading — even a PSA 9 beats raw
A Grade 9.5 Jonathan Kuminga #RS-JKU sells for $110 against $50.79 raw: a $59.21 spread, 2.2× the ungraded price. Even a PSA 9 ($100) 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.
