Worth grading — even a PSA 9 beats raw
A PSA 8.5 Mew sells for $1000 against $102 raw: a $898 spread, 9.8× the ungraded price. Even a PSA 9 ($817) 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.
