I've never done a price suggestion, but I just traded for this and I know the price here is pretty far off so please correct me if I do anything wrong so I can hopefully improve this and make a new submission! =)

I bought it for a memory leak tough stuff muffs - 52 keys, a pro ks australium minigun - about 32 keys, pro ks australium scattergun - about 38 keys, and a pro ks australium grenade launcher - about 23 keys which totals to 140 keys worth of items about 4 days ago.

There is also a listing on backpack.tf that was put up 2 days ago for 175 keys if that means anything.

I've contacted the other 2 owners of the hat through backpack.tf premium and both told me that they had no intention of selling theirs. I can re-add them and get screenshots if necessary.

I'm also just estimating the value off of what the seller I obtained it from was looking for. They were asking for 140 keys pure or about 150 in items. I don't have any screenshots of this but I can talk to him and screenshot it as proof if necessary. Thanks for reading! =)
