Worth grading — even a PSA 9 beats raw

A PSA 10 Shellos East Sea sells for $3,499 against $0.49 raw: a $3,499 spread, 7141× the ungraded price. Even a PSA 9 ($176) 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.
