I'm making a non-currency suggestion. Shocking I know.

Long story short. There are not many of these on the market and not too many trades going at the price within the range. People try to buy it at a low "quicksell" price and try to resell it high with no luck.

Disproving previous range and current trades

http://www.tf2outpost.com/trade/17235001 - B/O is 2.4 earbuds.*Disproves upper range*

http://www.tf2outpost.com/trade/15793935 - 2 months old. Last offer was two weeks : Tam O' Shanter Stormy with Killstreak weapons. Cannot give exact value due to KS weapons but it is still low. *Disproves lower range*

http://www.tf2outpost.com/trade/17972920 - 2 days old, bumped. Young trade

http://www.tf2outpost.com/trade/17858122 - 5 days old, no comments. Still kind of young

http://www.tf2outpost.com/trade/18037757 - Extremely young trade

Proof of new range
