Worth grading — even a PSA 9 beats raw

A PSA 10 Tentacruel sells for $325 against $49.54 raw: a $275 spread, 6.6× the ungraded price. Even a PSA 9 ($128) 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.
