Worth grading — even a PSA 9 beats raw

A CGC 10 Ken Griffey Jr #9SG sells for $2,688 against $240 raw: a $2,448 spread, 11× the ungraded price. Even a PSA 9 ($1,300) 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.
