https://backpack.tf/profiles/76561198053809624#!/compare/1635552000/1635897600 - The person who sold this for 51 had paid much more

https://marketplace.tf/items/tf2/612;5;u87 - $122.42 (66 Keys)

The untraceable sale was a bulk sale for the Translator. Given the dump from the first sale I linked to 51, neither of those should be used.

With all of the sales being much lower than 99, that'd suggest 99 is high.So excluding that sale

Actually, there was a sale at 50 Keys in this history that supports keeping 51 in the range - https://backpack.tf/item/11051503715

https://gladiator.tf/sales?item=Frostbite%20Little%20Buddy&at=2021-12-30T01:56:32.437Z

So 51 - 66 would work.

Taking 51-66
