Worth grading — even a PSA 9 beats raw
A PSA 9 Zekrom-GX sells for $66.84 against $25.83 raw: a $41.01 spread, 2.6× the ungraded price. Even a PSA 9 ($66.84) 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.
