Is it worth grading?
Worth grading — even a PSA 9 beats raw
A PSA 10 Kent Peterson #42 sells for $3,642 against $14.58 raw: a $3,628 spread, 250× the ungraded price. Even a PSA 9 ($549) 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.
