Worth grading — even a PSA 9 beats raw

A Grade 9.5 Guy Chouinard #340 sells for $34.00 against $0.81 raw: a $33.19 spread, 42× the ungraded price. Even a PSA 9 ($31.00) 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.
