Worth grading — even a PSA 9 beats raw
A Grade 9.5 Mind-Blown Sloan [Black] #72b sells for $77.00 against $8.24 raw: a $68.76 spread, 9.3× the ungraded price. Even a PSA 9 ($69.99) 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.
