Worth grading — even a PSA 9 beats raw
A PSA 10 Trevenant & Dusknoir-GX sells for $1,475 against $21.79 raw: a $1,453 spread, 68× the ungraded price. Even a PSA 9 ($135) 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.
