Worth grading — even a PSA 9 beats raw

A Grade 9.5 Curtis Martin [Interstate Refractors] #80 sells for $119 against $17.00 raw: a $102 spread, 7.0× the ungraded price. Even a PSA 9 ($108) 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.
