Worth grading — even a PSA 9 beats raw
A PSA 10 Mr. Stone's Project sells for $375 against $0.96 raw: a $374 spread, 391× the ungraded price. Even a PSA 9 ($32.89) 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.
