Worth grading — even a PSA 9 beats raw
A PSA 10 Tony Perez #58 sells for $1,872 against $14.99 raw: a $1,857 spread, 125× the ungraded price. Even a PSA 9 ($200) 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.
