Worth grading — even a PSA 9 beats raw
A Grade 9.5 Ken Griffey Jr. [Extra Edition] #28 sells for $134 against $50.32 raw: a $83.68 spread, 2.7× the ungraded price. Even a PSA 9 ($121) 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.
