Worth grading — even a PSA 9 beats raw
A CGC 10 Space Cadet Penguin [Promo Foil] #8 sells for $250 against $75.00 raw: a $175 spread, 3.3× the ungraded price. Even a PSA 9 ($125) 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.
