Worth grading — even a PSA 9 beats raw
A PSA 10 Mike Piazza #PP15 sells for $127 against $2.60 raw: a $124 spread, 49× the ungraded price. Even a PSA 9 ($60.69) 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.
