Worth grading — even a PSA 9 beats raw
A Grade 9.5 Mark Gubicza #430 sells for $67.00 against $1.59 raw: a $65.41 spread, 42× the ungraded price. Even a PSA 9 ($61.00) 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.
