Is it worth grading?
Worth grading — even a PSA 9 beats raw
A Grade 9.5 Mario Madness #21 sells for $36.00 against $7.83 raw: a $28.17 spread, 4.6× the ungraded price. Even a PSA 9 ($33.00) 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.
