Worth grading — even a PSA 9 beats raw
A PSA 10 Warren Rosar #138 sells for $1,288 against $4.75 raw: a $1,283 spread, 271× the ungraded price. Even a PSA 9 ($198) 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.
