6 month old price and rather outdated at that. It is currently valued higher than plasma's and hearts which doesn't seem very accurate. Christmas is also over and there isn't exacty a huge demand for this effect.

http://www.tf2outpost.com/trade/8058654 same hat owner got a top offer of what he values at 1.33

http://www.tf2outpost.com/trade/8776015 Selling bud and 5keys

http://www.tf2outpost.com/trade/8126439 offers of a bud+key and Planets Honcho around 1.5

http://www.tf2outpost.com/trade/8732827 Buyout 1.5

Around 1.5 seems to be the top price that the hat is selling for. Many are going for a decent bit lower with most trades lacking offers with substance most just have a couple bud to bud+ offers
