Worth grading — even a PSA 9 beats raw
A PSA 10 Ken Griffey Sr. #Sr. sells for $344 against $15.00 raw: a $329 spread, 23× the ungraded price. Even a PSA 9 ($66.55) 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.
