Worth grading — even a PSA 9 beats raw
A PSA 10 Tim Duncan [Xfractor] #21 sells for $488 against $81.47 raw: a $407 spread, 6.0× the ungraded price. Even a PSA 9 ($151) 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.
