Worth grading — even a PSA 9 beats raw
A Grade 9.5 Billie Jean King #C-BK sells for $193 against $140 raw: a $52.75 spread, 1.4× the ungraded price. Even a PSA 9 ($175) 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.
