Aces KE (~9) + Ghosts CK (~12.5) + C9 Tyrant's (~5) + SF Huntsman (~0.5) + 5 pure
Sale involved a GE TC, but it's very hard to tell whether it was an actual 1:1 as the original offer was a PE Brown Bomber + Paypal ( http://www.tf2outpost.com/trade/18383936 ), which means that money was probably added on top of either side.
Nevertheless, it had an untaken B/O of 22 for over a month.
