Worth grading — even a PSA 9 beats raw
A Grade 9.5 Darrell Porter #52 sells for $131 against $1.92 raw: a $129 spread, 68× the ungraded price. Even a PSA 9 ($119) 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.
