6-7 is a rough range of what this hat goes for. There are constant notable offers in this range. I think 7.5 isn't ready to be included here since it's a collecting offer which was also retracted, and considering the guy selling his for 7.5 buds pure for 2 months. So it's safer to put 7 as high end for now. Overpay and original prices used.
