http://www.tf2outpost.com/trade/18356238 Sold for 2 DBD Hat of Cardseseses (5 * 2)

I quote Polar:

Also want to note that the DBD hat of cards was closer to 5 in pure at the time of that trade - http://backpack.tf/vote/id/5336cf334dd7b8c90b8b47ee - there is a sale there at 5 in mostly pure. I think that sale value is closer to ~9-10

10 * 0.9 = 9
