Worth grading — even a PSA 9 beats raw
A PSA 10 Underground Lake sells for $1,910 against $10.46 raw: a $1,900 spread, 183× the ungraded price. Even a PSA 9 ($45.58) 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.
