There aren't many legit trades and I don't feel like sifting through all 3 pages. There are some people looking for 1 ref and higher, however no one is interested. There aren't any offers of less than .33 that aren't hidden (except the old one where the trader sold a bunch for one scrap) or more than .66. There are a few offers at .66 so I believe this range is decent for the time being, maybe if the range was a bit lower it woud be more relevant. Most of these trades are pretty new. I searched for people buying this, only found people buying at 1 scrap. None of the comments are recent. =( Not 100% sure about this, but upvote for now.

Old price is outdated, now this is a collectors item ill upvote.

Upvoted this its the coolest expired item by next christmas it will be a key or 2 i bet

http://www.tf2outpost.com/trade/6152961 ~ .44 each offer

http://www.tf2outpost.com/trade/6990847 b/o key for all ~.44 max

Looks like it could use a boost but .66 is too high. Most links either have no offers or have super high buyouts of 1 ref+
