Worth grading — even a PSA 9 beats raw
A PSA 10 Ken Dryden #330 sells for $317 against $3.59 raw: a $314 spread, 88× the ungraded price. Even a PSA 9 ($61.00) 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.
