Worth grading — even a PSA 9 beats raw
A Grade 9.5 Nathan Colbert #72 sells for $189 against $17.50 raw: a $172 spread, 11× the ungraded price. Even a PSA 9 ($172) 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.
