Quick and dirty suggestion, fresh from ya boi NyQuil.

Two recent pure sales took place on this outdated 1 of 3 Unusual. Other 2 existences of this hat haven't been traded for 4+ Months and the only other sale on the particular hat I sold took place in February.

Sale #1 - 22 Keys

I bought this for 22 Keys.

Sale #2 - 26 Keys

Sold this to my friend Draethon for 26 Keys. I asked him before making the suggestion and he has no intention of ever trading the hat. So for the sake of accuracy, I am dropping the hat. Compare link isn't too helpful here, as he bought the keys from Marketplace.tf then insta-traded me.
