Worth grading — even a PSA 9 beats raw
A Grade 9.5 Kevin Durant [Silver Refractor] #89 sells for $110 against $18.80 raw: a $91.20 spread, 5.9× the ungraded price. Even a PSA 9 ($100) 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.
