Worth grading — even a PSA 9 beats raw
A Grade 9.5 Invaded by Alien Energy #83b sells for $88.00 against $4.99 raw: a $83.01 spread, 18× the ungraded price. Even a PSA 9 ($79.66) 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.
