Untrace but looks like quicksell to bot: https://gladiator.tf/listings/60cca1825b89c8ced2263a81 (actual buy order not found)

https://backpack.tf/profiles/76561198841279602#!/compare/1623888000/1623974400

https://backpack.tf/profiles/76561197999553390#!/compare/1623801600/1624060800

Probably for around ~49k, just a touch below buyers so excluding.

Can't really trace here, but bot B/O at ~57k: https://gladiator.tf/listings/61019c7501ba43d1f7659432

https://backpack.tf/profiles/76561198092031974#!/compare/1627171200/1627776000

https://backpack.tf/profiles/76561198841279602#!/compare/1627344000/1627516800

Given no way to contact bot owner https://steamcommunity.com/id/24our7even/, assuming there was no negotiation. Going to take this as a 57k sale.

Untrace, probably later sold for buy orders:

Very possibly a 49k sale from QS.store bot: https://gladiator.tf/listings/60da917d3e247539a66fff5e

https://backpack.tf/profiles/76561198057047713#!/compare/1624838400/1624924800

below buyers, excluding

Looks like the hat could have been immediately sold back to another bot for 49.5k?: https://gladiator.tf/listings/60da917d3e247539a66fff5e

https://backpack.tf/profiles/76561198057047713#!/compare/1624924800/1625011200

~57k: https://gladiator.tf/listings/610c43e515a02aced9adef59

Numerous sales around the 49-50k are countered by buyers. Two 57k sales so taking that.
