Is it worth grading?
Worth grading — even a PSA 9 beats raw
A PSA 10 Harmon Killebrew #120 sells for $28,800 against $5.57 raw: a $28,794 spread, 5171× the ungraded price. Even a PSA 9 ($810) 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.
