Worth grading — even a PSA 9 beats raw
A Grade 9.5 Blair Chapman #21 sells for $124 against $1.08 raw: a $123 spread, 115× the ungraded price. Even a PSA 9 ($113) 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.
