Worth grading — even a PSA 9 beats raw
A Grade 9.5 Ken Griffey Jr. #KG sells for $9,394 against $6,490 raw: a $2,904 spread, 1.4× the ungraded price. Even a PSA 9 ($8,540) 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.
