Conclusions: I really hate to base prices on duped unusuals. I think the guy selling the duped one on the market would take 2.3 pure (added a bunch of people offering 2-2.2 pure). However, he has had offers of 2.85-3.1 in unusuals and clean ones have sold in the last month for 3 pure and 2.8 in unusuals, so setting low end at 2.8 in unusuals = 2.5 pure and high end at 3 pure.
