https://marketplace.tf/items/tf2/30378;5;u58 - There was a Heer's sale for $89.99 (~49 Keys)

https://backpack.tf/profiles/76561198118794852#!/compare/1722643200/1722988800 - Another for 35 Keys + ~8 Keys of items

43 - 49 for that makes sale 1 46 Keys. I agree 200 should be the outlier, so 46 - 60 would work here.

Going 46 Keys - 60 Keys or an average of 53 Keys flat!

Feedback welcome! Thanks!
