Worth grading — even a PSA 9 beats raw

A PSA 10 Harmon Killebrew #515 sells for $6,742 against $34.88 raw: a $6,707 spread, 193× the ungraded price. Even a PSA 9 ($1,018) 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.
