Worth grading — even a PSA 9 beats raw

A PSA 10 Kristaps Porzingis #18 sells for $1,763 against $463 raw: a $1,300 spread, 3.8× the ungraded price. Even a PSA 9 ($600) 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.
