Worth grading — even a PSA 9 beats raw

A PSA 10 Jack Christiansen #129 sells for $16,430 against $67.99 raw: a $16,362 spread, 242× the ungraded price. Even a PSA 9 ($2,463) 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.
