Not that many trades with offers that aren't low craft numbers, so here we go. I know it's early but let's establish a price so later on we can change it easier and more realistically.

http://www.tf2outpost.com/trade/8369050 - offer of grey muffs + a refined (about 4 refined, but I've seen the same person offer the grey muffs + a rec)

http://www.tf2outpost.com/trade/8372565 - selling for 2.66, no luck.

http://www.tf2outpost.com/trade/8396879 - selling for 3 refined, has interest from who I presume is a craft # collector.

I'll post new proof when new trades emerge.
