Worth grading — even a PSA 9 beats raw

A PSA 10 Bob & Bill Shantz #139 sells for $1,040 against $4.76 raw: a $1,035 spread, 219× the ungraded price. Even a PSA 9 ($996) 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.
