Worth grading — even a PSA 9 beats raw
A PSA 10 Kate Martin #59 sells for $48.00 against $11.77 raw: a $36.23 spread, 4.1× the ungraded price. Even a PSA 9 ($39.88) 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.
