Is it worth grading?
Worth grading — even a PSA 9 beats raw
A PSA 10 Ken Griffey #320 sells for $217 against $2.00 raw: a $215 spread, 109× the ungraded price. Even a PSA 9 ($80.35) 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.
