Worth grading — even a PSA 9 beats raw
A PSA 10 Sam Perkins #31 sells for $147 against $1.40 raw: a $146 spread, 105× the ungraded price. Even a PSA 9 ($52.00) 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.
