Worth grading — even a PSA 9 beats raw
A PSA 10 Iga Swiatek #GSR-ISK sells for $706 against $143 raw: a $563 spread, 4.9× the ungraded price. Even a PSA 9 ($246) 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.
