Worth grading — even a PSA 9 beats raw
A PSA 10 San-Gorou sells for $1,488 against $0.20 raw: a $1,487 spread, 7438× the ungraded price. Even a PSA 9 ($800) 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.
