https://backpack.tf/profiles/76561198186643130#!/compare/1514937600/1515196800 ~ sold for a circling tf logo trophy belt? though histories dont match, sale would be 21 with the seller mini tho

Sold #3:

https://backpack.tf/profiles/76561198236788328#!/compare/1512000000/1512086400 ~ sold with a silver cyclone Posedown ~ sellers at 10 https://i.imgur.com/1GLTIIv.png for 41 keys, making this 31.

Sold #4:

https://backpack.tf/profiles/76561198128803260#!/compare/1516579200/1516752000 ~ sold for around 20 keys. Can't tell. User quickly bought a vivid plasma conno with the pure after the sale https://backpack.tf/profiles/76561198066308681#!/compare/1516665600/1516752000 , so they must of paid at least 18 (higher then quickbuyers), so I'll count it as 22.5, but since it's not a certain sale I'll just stick to 21 and I'd say 31 is an outlier.
