Worth grading — even a PSA 9 beats raw

A Grade 9.5 Ken Griffey Jr #10 sells for $2,090 against $350 raw: a $1,740 spread, 6.0× the ungraded price. Even a PSA 9 ($1,900) 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.
