Needs a bit of a bump down. There are plenty of people who haven't sold theirs at 2 ref. That's the lowest price that a lot of people are selling for, so it seems fine for now as a low end. See the previous suggestion for proof of the high end.

I think there are enough sellers at 2 ref to safely include it in the price range. Sales above it are rare, but I didn't want to change it too drastically after the other suggestion was just accepted.
