Worth grading — even a PSA 9 beats raw
A Grade 9.5 Roberto Clemente #309 sells for $3,157 against $107 raw: a $3,050 spread, 30× the ungraded price. Even a PSA 9 ($2,870) 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.
