Worth grading — even a PSA 9 beats raw

A Grade 9.5 John McEnroe [Blue Refractor] #SS-JM sells for $211 against $130 raw: a $81.00 spread, 1.6× the ungraded price. Even a PSA 9 ($192) 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.
