Worth grading — even a PSA 9 beats raw
A Grade 9.5 Mike Piazza #142 sells for $147 against $3.34 raw: a $144 spread, 44× the ungraded price. Even a PSA 9 ($134) 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.
