Worth grading — even a PSA 9 beats raw

A PSA 10 ボーマンダEX sells for $265 against $42.55 raw: a $223 spread, 6.2× the ungraded price. Even a PSA 9 ($68.52) 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.
