Worth grading — even a PSA 9 beats raw

A Grade 9.5 Tommie Sisk #21 sells for $68.00 against $17.67 raw: a $50.33 spread, 3.8× the ungraded price. Even a PSA 9 ($62.11) 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.
