Worth grading — even a PSA 9 beats raw

A Grade 9.5 Cal Koonce #34 sells for $175 against $6.58 raw: a $168 spread, 27× the ungraded price. Even a PSA 9 ($160) 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.
