Worth grading — even a PSA 9 beats raw
A PSA 10 Boom Boom Geoffrion #48 sells for $2,801 against $15.90 raw: a $2,785 spread, 176× the ungraded price. Even a PSA 9 ($227) 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.
