Worth grading — even a PSA 9 beats raw
A Grade 9.5 Iga Swiatek [Green Sapphire] #10 sells for $37.00 against $5.62 raw: a $31.38 spread, 6.6× the ungraded price. Even a PSA 9 ($33.81) 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.
