SOLD

http://www.tf2outpost.com/trade/23068299 -. Bought from a user that has never made a trade on OP, (Very) quick selling for 25 keys. Appears from BPTF history that it sold for 23 keys.

http://www.tf2outpost.com/trade/23079479 - Just bought. Previous owner was “unhelpful”. Could not add this user to ask. However, backpack value decreased by about 67 keys, so that is the assumed purchase price. Looking for CSGO offers.

http://www.tf2outpost.com/trade/22870832 - planets tossle ~1.7

http://www.tf2outpost.com/trade/23079479 - nuts modest ~1.5

Sales at 1.1, 1.4, 1.5, 1.6, 1.6, 1.7, 1.7, 2.2. I'd probably call 1.1 and 2.2 as outliers on either end and make the range something like 1.5-1.7. If other sales pop up at 1.7+ I guess I could be convinced that 2.2 should be in the range.
