Worth grading — even a PSA 9 beats raw
A PSA 10 Walter Stewart #121 sells for $8,349 against $25.50 raw: a $8,324 spread, 327× the ungraded price. Even a PSA 9 ($2,002) 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.
