Worth grading — even a PSA 9 beats raw

A PSA 10 Porygon-Z sells for $1,050 against $3.14 raw: a $1,047 spread, 334× the ungraded price. Even a PSA 9 ($73.28) 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.
