Worth grading — even a PSA 9 beats raw

A Grade 9.5 Tim Duncan #8 sells for $6,716 against $1,450 raw: a $5,266 spread, 4.6× the ungraded price. Even a PSA 9 ($6,105) 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.
