Worth grading — even a PSA 9 beats raw
A PSA 10 Cooper Flagg [Green Refractor] #BD-21 sells for $900 against $300 raw: a $600 spread, 3.0× the ungraded price. Even a PSA 9 ($467) 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.
