Worth grading — even a PSA 9 beats raw
A Grade 9.5 Peter Mahovlich #187 sells for $109 against $1.74 raw: a $107 spread, 63× the ungraded price. Even a PSA 9 ($99.00) 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.
