Worth grading — even a PSA 9 beats raw

A Grade 9.5 Mikal Bridges #MKB sells for $141 against $21.53 raw: a $119 spread, 6.5× the ungraded price. Even a PSA 9 ($128) 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.
