w/ 10 keys for a CH Rotation

Mini on Rotation:

https://backpack.tf/profiles/76561197989136498#!/compare/1520380800/1520467200

with 15 keys and a victory lap FOD for a strange PE rotation, indate at 150

Victory FOD micro (legit the only one I could get):

https://backpack.tf/profiles/76561198156052965#!/compare/1521244800/1521331200

27 pure. Buyers at 23, seller at 30 for 2 days, this seems reasonable enough

150 - 27 - 15 = 108

BUT theres an unsold for 100 https://imgur.com/a/kRtmLkE , so capping there at 100.

so finally 100-10 = 90

Sale 3:

https://backpack.tf/profiles/76561198069286674#!/compare/1522454400/1522800000

with 11 keys in strange sweets for a GE front runner, indate @ 68

68 - 11 = 57

thats all I could find, counting 90 as outlier.

Also seller on marketplace is selling for 109.99 USD which is roughly 56 keys @ 1.97 per key so this seems fair.
