Worth grading — even a PSA 9 beats raw
A PSA 10 Tapu Koko-GX sells for $50.00 against $2.44 raw: a $47.56 spread, 20× the ungraded price. Even a PSA 9 ($31.69) 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.
