Worth grading — even a PSA 9 beats raw
A PSA 10 Checklist #18 sells for $985 against $1.14 raw: a $984 spread, 864× the ungraded price. Even a PSA 9 ($821) 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.
