Worth grading — even a PSA 9 beats raw
A Grade 9.5 Tyrone Corbin #169 sells for $29.00 against $1.39 raw: a $27.61 spread, 21× the ungraded price. Even a PSA 9 ($26.42) 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.
