http://www.tf2outpost.com/trade/13655640 sold for the Blizzardy Storm Trophy Belt,and this is the link for proof of the hat http://www.tf2outpost.com/trade/13692697 owners can be seen the the history of the hat(trophy belt)-original price for the trophy belt is 1.3-1.7

So.

2.3x0.9 overpay= 2.1

2.2x0.9 overpay= 2

1.5x0.9 overpay=1.3

So I suggest to make a price range of 1.3-2.1 for this hat.
