very high

https://backpack.tf/profiles/76561198954470051#!/compare/1605657600/1605744000 - The KE sold for 60 Keys + 27 Refined (creds Shuffle Spy)

This was the sale of the buyer in the Naggen sale. It is at buy orders but it should be reasonable to take this since H was fine getting that much pure from the KE for that trade. The other sales are really weird and not super usable.

210 - 60.5 - 5 = ~145

@Werslgumg, 145 - 160 will work here. You will need to close this and resuggest at that range.
