Worth grading — even a PSA 9 beats raw
A PSA 10 Stephen Curry [Purple] #12 sells for $52.00 against $3.38 raw: a $48.62 spread, 15× the ungraded price. Even a PSA 9 ($32.00) 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.
