Strong grading candidate — 4.7× premium in PSA 7
A PSA 7 Mew sells for $1,400 against $300 raw: a $1,100 spread, 4.7× the ungraded price. A PSA 9 ($289) sells for less than raw, so anything short of a 10 loses money. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.
