Worth grading — even a PSA 9 beats raw

A Grade 9.5 Darrell Porter #188 sells for $30.00 against $1.59 raw: a $28.41 spread, 19× the ungraded price. Even a PSA 9 ($26.97) 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.
