Using Specialized Killstreak Australium Frontier Justice at 10 keys.

Bp.tf Classifieds

Highest buyers in classifieds at 10 keys.

Plus there are sales from Bot.tf at +10keys: Bot.tf stats

So 10 keys for the Specialized Killstreak Australium Frontier Justice + 3 pure Keys = 13 Keys.

First unusual suggestion, please tell me if I did something wrong.
