Worth grading — even a PSA 9 beats raw
A PSA 10 Wilt Chamberlain [Purple & Gold Snakeskin] #300 sells for $150 against $64.11 raw: a $85.89 spread, 2.3× the ungraded price. Even a PSA 9 ($125) 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.
