Worth grading — even a PSA 9 beats raw
A Grade 9.5 Duncan Robinson [Purple] #DRB sells for $137 against $7.22 raw: a $130 spread, 19× the ungraded price. Even a PSA 9 ($125) 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.
