https://backpack.tf/item/4121189850

https://bot.tf/stats/listings/4R3ZGJ2M - the buyer was significantly higher than other buy orders, and awfully close to sellers at the time. As it stands now, the buyers have dropped even further. No need to exclude this sale or anything lower.

https://backpack.tf/item/4114405897

https://i.imgur.com/yu8ej3v.png - Given how close sellers and buyers are on the taunt, it shouldn’t need to be looked into. This’ll end up being around ~2.75 keys, or even 3.

https://bot.tf/stats/listings/4EXQO76Y - B/O of 58

Buyer most likely sold the All-Father for keys then spent the keys on the crone’s dome, which would add another ~4 keys to the trade. If not, this sale would be 57. Doesn’t matter as it fits in the range either way.
