Untraceable, Maybe sold for keys?

Taking 135 flat.

K1ng's info:

It was traded back after the Beams Wrap sale for a MG Wrap:

https://backpack.tf/profiles/76561198410760897#!/compare/1525392000/1525824000

https://backpack.tf/profiles/76561198043936328#!/compare/1525737600/1525824000

Further proves that both sales are outliers. However, it has been listed on marketplace for a while at ~110 keys:

So I would go with 110-135 here.
