Worth grading — even a PSA 9 beats raw

A PSA 10 Dave Keon #279 sells for $179 against $1.74 raw: a $177 spread, 103× the ungraded price. Even a PSA 9 ($55.00) 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.
