Sale at 40 is on the low side IMO, sold pretty quickly. The other sale at 40 in the last suggestion doesn't line up as far as I can tell, the items don't appear to have been traded together so I am ignoring it. http://backpack.tf/vote/id/55c974b8b98d88fd018b4594

That leaves sales at 50, 59, 60, 62, so going to go for that on the range. Feedback is welcome.
