Worth grading — even a PSA 9 beats raw
A Grade 9.5 Jack Marin #122 sells for $550 against $1.75 raw: a $548 spread, 314× the ungraded price. Even a PSA 9 ($500) 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.
