http://www.tf2outpost.com/trade/25397956 http://gyazo.com/5b4bebd994e72af59cbe9ecda98f88ea - sold for peace thirst blood + 72' deep fried = 59 x 0.9 = 53 keys

http://www.tf2outpost.com/trade/25350581 - sold for stormy vintage tyrolean + 2 buds = 43 x 0.9 = 39 keys

53 Seems like an outlier now, the rest of the sales seem to fit though. 34-47 Keys should be fine.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
