Worth grading — even a PSA 9 beats raw
A Grade 9.5 Michael Porter Jr. [Patch Autograph] #313 sells for $990 against $50.00 raw: a $940 spread, 20× the ungraded price. Even a PSA 9 ($900) 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.
