Worth grading — even a PSA 9 beats raw
A Grade 9.5 Mike Piazza #147 sells for $41.00 against $6.81 raw: a $34.19 spread, 6.0× the ungraded price. Even a PSA 9 ($37.69) 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.
