Worth grading — even a PSA 9 beats raw
A PSA 10 Thundurus-EX sells for $233 against $2.44 raw: a $230 spread, 95× the ungraded price. Even a PSA 9 ($29.40) 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.
