Worth grading — even a PSA 9 beats raw
A PSA 10 Mark Parent #358 sells for $152 against $2.88 raw: a $149 spread, 53× the ungraded price. Even a PSA 9 ($99.99) 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.
