Is it worth grading?
Worth grading — even a PSA 9 beats raw
A Grade 9.5 Boom Boom #78 sells for $98.00 against $8.56 raw: a $89.44 spread, 11× the ungraded price. Even a PSA 9 ($89.00) 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.
