Worth grading — even a PSA 9 beats raw
A Grade 9.5 Boom Boom Geoffrion #33 sells for $381 against $21.15 raw: a $360 spread, 18× the ungraded price. Even a PSA 9 ($346) 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.
