Is it worth grading?

Worth grading — even a PSA 9 beats raw

A CGC 9 Mamoswine sells for $47.35 against $1.89 raw: a $45.46 spread, 25× the ungraded price. Even a PSA 9 ($30.00) 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.
