Worth grading — even a PSA 9 beats raw
A PSA 10 Alex Kellner #280 sells for $1,230 against $5.80 raw: a $1,225 spread, 212× the ungraded price. Even a PSA 9 ($406) 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.
