Worth grading — even a PSA 9 beats raw

A Grade 9.5 Floyd Mayweather Jr. [Gold Refractor] #33 sells for $138 against $99.99 raw: a $38.01 spread, 1.4× the ungraded price. Even a PSA 9 ($125) 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.
