Worth grading — even a PSA 9 beats raw

A PSA 8.5 Master Ball sells for $61.99 against $0.87 raw: a $61.12 spread, 71× the ungraded price. Even a PSA 9 ($39.00) 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.
