Tried to sell mine for five days at 2.5, then 2 keys one Ref. No offers, at all. Eventually traded it 1:1 with Lord Cock.

Agreed on this price, they simply don't sell at 2.5, 2 is pushing it.

I agree, I've sold a few at 2 keys, but never more. 2.5 is a bit high at this point.

I just recently put up a trade offering 5 ref for one, and it was completed within the hour. It is definitely getting more difficult to sell for 2.5 keys; 2 keys seems like the better price.

Sadly, they have dropped it seems. I'm not getting mine sold for 2.5 keys. Hopefully 2 keys will get it done :(

Everyone seems to agree on this one, evidence is clear. Upvoted.

were these 2.5 keys all along?, i have never seen anyone asking or buying for more than 2 keys or 5 ref, UPVOTE

Easy to find lower than 2.5, but not sure about 2 keys.

Here I asked how much did he buy it for: http://www.tf2outpost.com/trade/6039981#/22879102

Hard to sell indeed; took me about a week to sell, and I finally got it sold for 5 ref and a dirty.

2 keys is a bit low. These still fetch more than 2 keys. A range would be better.
