i think 13-15 is fine. Those guys might be overpaying a bit. 3 Sold today for 13.

Theres B/O of 16 out there and didn't offer over 15 keys.

The guy who offered 15 keys was a bit overpaying and also there's no proof of 16 keys. I would say 13-15 keys is the price right now (I am the owner of the 2nd trade :P)

I wouldnt go as far and say that it's worth 15 keys just yet, 13-14 is fine. In a little bit it should rise with all of the crate 40 items

13- 15 is fine, at least for the rest of these week a think, who now migth get up a little bit more as it did last week.

but the current price range is ok

Slowly rising in value right now, due to crate #40's removal from the "can drop" list when #50 comes out soon. Will do a big price jump again when it happens.

http://www.tf2outpost.com/trade/4846184 14 keys (Assuming the Track is 1 key)

http://www.tf2outpost.com/trade/3088372 14 keys

Wasn't hard to find some with buyouts below 15 keys. Too early for this price bump.
