https://backpack.tf/item/9542322159 - professional killstreak, sold for 47 pure, seems way too high.

https://backpack.tf/item/9916112361 - the only non-killstreak frozen aurora sniper rifle, 20 pure.

Taking 20, I haven't been able to find the scm sale but I'm sure it's going to be around 20 pure, considering all frozen aurora warpaints are selling for around 20 pure.
