Worth grading — even a PSA 9 beats raw

A PSA 10 Ken Dryden #155 sells for $967 against $7.60 raw: a $959 spread, 127× the ungraded price. Even a PSA 9 ($119) 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.
