Worth grading — even a PSA 9 beats raw
A PSA 10 Kobe Bryant #ZB8 sells for $305 against $53.53 raw: a $251 spread, 5.7× the ungraded price. Even a PSA 9 ($107) 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.
