Worth grading — even a PSA 9 beats raw

A PSA 10 Mike Riordan #102 sells for $208 against $1.76 raw: a $206 spread, 118× the ungraded price. Even a PSA 9 ($129) 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.
