Worth grading — even a PSA 9 beats raw
A PSA 10 Phil Masi #19 sells for $5,443 against $21.66 raw: a $5,421 spread, 251× the ungraded price. Even a PSA 9 ($293) 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.
