Worth grading — even a PSA 9 beats raw
A PSA 10 Bob Johnson #20 sells for $5,539 against $16.16 raw: a $5,523 spread, 343× the ungraded price. Even a PSA 9 ($830) 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.
