Worth grading — even a PSA 9 beats raw
A PSA 10 Stephon Marbury #1 sells for $2,325 against $89.26 raw: a $2,236 spread, 26× the ungraded price. Even a PSA 9 ($1,750) 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.
