Worth grading — even a PSA 9 beats raw
A PSA 10 Ron Guidry #656 sells for $1,434 against $3.00 raw: a $1,431 spread, 478× the ungraded price. Even a PSA 9 ($1,195) 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.
