Worth grading — even a PSA 9 beats raw
A Grade 9.5 Checklist 133-231 #31 sells for $2,326 against $150 raw: a $2,176 spread, 16× the ungraded price. Even a PSA 9 ($2,114) 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.
