Sale 2 was the Counterfeit + 13 Keys + ~1 Key of Items for a Frozen Icefall Beenie (85 Keys)

https://backpack.tf/profiles/76561198275012706#!/compare/1583020800/1583107200 - The Beenie then sold for the Scattergun and Keys

https://imgur.com/a/nkjoKwA - This would have been capped by the buyout of 64 Keys

https://imgur.com/a/OKZ3vnq - With 2 sellers at 55/56 Keys (one of which is 28 days old), and since the person who paid 60 dumped it to zol a day later, I'd exclude 60 as well and go 48 - 50.
