Worth grading — even a PSA 9 beats raw

A PSA 10 Johnny Antonelli [White Back] #138 sells for $1,328 against $7.75 raw: a $1,320 spread, 171× the ungraded price. Even a PSA 9 ($204) 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.
