Worth grading — even a PSA 9 beats raw

A Grade 9.5 Professor X #EX15 sells for $77.00 against $2.15 raw: a $74.85 spread, 36× 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.
