I am surprised anyone would even want one of these :P Lower than Orb. Fire and Bubbling...

Sale 1:

http://www.tf2outpost.com/trade/24158153 http://backpack.tf/profiles/76561198062565378?time=1419148800 to http://backpack.tf/profiles/76561198062565378?time=1419580800 Sold for a N&B Beak, 1.4 buds, 1.3 buds after overpay. (Note that the buyer wasn't banned at the time)

Final sale value: 1.3 buds

Sale 2:

http://www.tf2outpost.com/trade/24336310 http://backpack.tf/profiles/76561198069892390?time=1419667200 to http://backpack.tf/profiles/76561198069892390?time=1419753600 Sold for 18 keys/1.4 buds pure, as buds were 13 keys at the time of sale.

Final sale value: 1.4 buds

The other two of the three hats haven't moved in more than 3 months. With sales at 1.3 at 1.4 buds, 1.3 to 1.4 buds should suffice.
