Worth grading — even a PSA 9 beats raw
A PSA 10 John Koniszewski #24 sells for $6,814 against $24.99 raw: a $6,789 spread, 273× the ungraded price. Even a PSA 9 ($1,023) 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.
