Worth grading — even a PSA 9 beats raw

A PSA 10 Bob Pulford #4 sells for $20,067 against $96.64 raw: a $19,970 spread, 208× the ungraded price. Even a PSA 9 ($3,014) 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.
