Worth grading — even a PSA 9 beats raw
A PSA 10 Ken Heintzelman #148 sells for $1,339 against $5.60 raw: a $1,333 spread, 239× the ungraded price. Even a PSA 9 ($500) 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.
