Worth grading — even a PSA 9 beats raw

A PSA 8 Magnezone sells for $137 against $0.97 raw: a $136 spread, 141× the ungraded price. Even a PSA 9 ($75.63) 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.
