went on marketplace and found 2 sales. one for 71.99 on march 10, 2019 and another for 47.62 on april 28, 2019

https://marketplace.tf/items/30067;5;u15

the average price for keys was 1.8 on march 10. so 71.99 / 1.8 = 39.99 rounding to 40

https://marketplace.tf/items/5021;6

https://gyazo.com/c3469a712c776a949ed4d5f281cef872

40 keys

on april 28, the average price was also 1.8 so same procedure.

47.62 / 1.8 = 26.45 this is too low i will not be using it (buyers at higher)

https://gyazo.com/9d96a9f60d3d562361651b5cd60ebc22

so i have sales at 45, 45, 40 and 26.45. making a range of 40-45 and excluding 26.45 as a low outlier.
