Sold for 24 keys.

SALE #2 = invalid

https://backpack.tf/profiles/76561198091502579#!/compare/1527465600/1527638400

Bought through a buy order for ~17 keys. Also countered by current buy orders.

SALE #3 = invalid

https://backpack.tf/profiles/76561198405901937#!/compare/1527379200/1527465600

https://backpack.tf/profiles/76561198143574438#!/compare/1526774400/1528934400

Sold for 18 keys. Excluding for 2 reasons. A) Low, close to buyers at 17 keys, B) later resold for 17 pure, so would make no sense to include this.

SALE #4 = invalid

https://backpack.tf/profiles/76561198042054674#!/compare/1528502400/1529539200

Untrace. Though, likely quickbought.
