Is it worth grading?
Worth grading — even a PSA 9 beats raw
A PSA 10 World Series Game 7 [Mazeroski's Homer Wins It] #312 sells for $2,373 against $13.00 raw: a $2,360 spread, 183× the ungraded price. Even a PSA 9 ($362) 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.
