Worth grading — even a PSA 9 beats raw
A Grade 9.5 Jim Slaton #29 sells for $36.00 against $1.00 raw: a $35.00 spread, 36× the ungraded price. Even a PSA 9 ($33.00) 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.
