Sale 5:

Sold to a bot for 15 keys (Buyer’s end)

Sale 6:

Most likely sold for 15 keys + some metal

https://backpack.tf/profiles/76561198141187659#!/compare/1735171200/1735257600

https://backpack.tf/item/3943253755

15 of the 16 keys on the buyer’s end went to a different bot owned by the same guy that owns the bot on the seller’s end here, + some metal matches with the owner of both bots. Haven’t counted all the metal for my sanity, but this’ll either be 15 or 16 keys here.

23 - outdated

Excluding the outdated sales, 15-19 seems like a clear winner here. If we were to look at the outdated sales, 23 would be invalid since it re-sold for less, but it would also probably be worth including 12 into the range. Highest buyer is ~9 keys. That being said, we have a decent volume of recent sales to use, and they all point to a clear common trading point, so I’ll stick with the 15-19 key range here.

Taking 15-19 keys.
