Worth grading — even a PSA 9 beats raw

A PSA 10 Dual Ball sells for $44.50 against $2.00 raw: a $42.50 spread, 22× the ungraded price. Even a PSA 9 ($125) 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.
