Worth grading — even a PSA 9 beats raw

A Grade 9.5 Sleepwalker #52 sells for $44.00 against $1.97 raw: a $42.03 spread, 22× the ungraded price. Even a PSA 9 ($39.99) 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.
