Is Zurg [100-Year Diamond] #28 worth grading?

Worth grading — even a PSA 9 beats raw

A Grade 9.5 Zurg [100-Year Diamond] #28 sells for $760 against $302 raw: a $458 spread, 2.5× the ungraded price. Even a PSA 9 ($691) 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.

Raw (NM): $302
Grade 9.5: $760
PSA 9: $691
