Worth grading — even a PSA 9 beats raw
A Grade 9.5 Stephon Marbury #GJ33 sells for $248 against $152 raw: a $96.40 spread, 1.6× the ungraded price. Even a PSA 9 ($225) 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.
