Worth grading — even a PSA 9 beats raw
A Grade 9.5 Boom Boom Geoffrion #29 sells for $355 against $26.47 raw: a $329 spread, 13× the ungraded price. Even a PSA 9 ($323) 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.
