Worth grading — even a PSA 9 beats raw
A PSA 10 Do You Know 1990 #3 sells for $1,185 against $26.25 raw: a $1,159 spread, 45× the ungraded price. Even a PSA 9 ($207) 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.
