Worth grading — even a PSA 9 beats raw

A Grade 9.5 Ben Chapman #130 sells for $4,950 against $225 raw: a $4,725 spread, 22× the ungraded price. Even a PSA 9 ($4,500) 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.
