I could only track down 2 concrete sales in the last 3 months...this hat doesn't seem to move fast.

Sale 1:

Sold with C9 Hetman's Headpiece(~.9) for Eerie O. Fire El Jefe(~4.8)

4.8*.9(overpay)= 4.3

4.4-.9 = 3.4 buds

Sale 2:

Sold for a Terror-watt Officer's Ushanka(~1.9) 1.7 with overpay

Before: http://backpack.tf/profiles/76561198039326143?time=1405666800

After: http://backpack.tf/profiles/76561198039326143?time=1406703600

The range is kinda big, but this hat really doesn't get traded often...any comments, criticism etc is more than appreciated.
