Worth grading — even a PSA 9 beats raw
A Grade 9.5 Brooks Robinson sells for $172 against $2.19 raw: a $170 spread, 79× the ungraded price. Even a PSA 9 ($156) 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.
