Worth grading — even a PSA 9 beats raw

A PSA 10 Jack Knott #68 sells for $6,588 against $14.06 raw: a $6,574 spread, 469× the ungraded price. Even a PSA 9 ($5,490) 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.
