#1

Untraceable

https://backpack.tf/profiles/76561198867788044#!/compare/1548633600/1548720000

https://backpack.tf/profiles/76561198342161127#!/compare/1548547200/1548633600

Only the 10 ref matches (none of the keys on the buyer’s end do, trust me, I checked)

#2

Sold for Footprints BoA

https://backpack.tf/profiles/76561198422289124#!/compare/1550275200/1550361600

https://backpack.tf/profiles/76561198146939162#!/compare/1550188800/1550361600

Not worth looking into. This BoA in particular doesn’t have any mini’s anyway.

#3

Sold with 2 keys? for Holy Grail Scotsman’s Stagger

https://backpack.tf/profiles/76561198279980264#!/compare/1549670400/1550361600

https://backpack.tf/profiles/76561198423300219#!/compare/1550361600/1550448000

I’m not confident that only 2 keys were added here, Would end up being too high if it were the case anyways. Excluding.

#4

Sold for 6 keys?

https://backpack.tf/profiles/76561198160193920#!/compare/1550620800/1550793600

https://backpack.tf/profiles/76561197963500354#!/compare/1550534400/1550620800

I’m sure there was some metal involved. Either way, this sale is being excluded.
