Worth grading — even a PSA 9 beats raw

A Grade 9.5 Luis Tiant #270 sells for $99.00 against $6.35 raw: a $92.65 spread, 16× the ungraded price. Even a PSA 9 ($89.99) 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.
