Worth grading — even a PSA 9 beats raw

A PSA 10 Dowsing Machine sells for $140 against $7.23 raw: a $132 spread, 19× the ungraded price. Even a PSA 9 ($115) 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.
