Worth grading — even a PSA 9 beats raw

A PSA 10 Cal Gardner #30 sells for $4,320 against $8.00 raw: a $4,312 spread, 540× the ungraded price. Even a PSA 9 ($268) 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.
