Worth grading — even a PSA 9 beats raw
A Grade 9.5 Ross Grimsley #1 sells for $48.00 against $2.75 raw: a $45.25 spread, 17× the ungraded price. Even a PSA 9 ($43.29) 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.
