Worth grading — even a PSA 9 beats raw

A PSA 10 Ken Dryden #150 sells for $413 against $4.51 raw: a $408 spread, 92× the ungraded price. Even a PSA 9 ($170) 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.
