Worth grading — even a PSA 9 beats raw
A Grade 9.5 Tim Duncan [Platinum Medallion] #131P sells for $9,857 against $2,114 raw: a $7,743 spread, 4.7× the ungraded price. Even a PSA 9 ($8,961) 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.
