Just traded this Virdescent Peeper Patriot Peak to Sir.Lucky for 300 keys, an Australium Grenade Launcher and a Twisted Radiance El Mostacho.

History (slightly less keys since i bought stuff immediately after): https://backpack.tf/profiles/76561198063952058#!/compare/1649376000/1660262400

In past 30 days Strange Australium Grenade Launcher was sold for average of 21.5-22.5 keys in the past 30 days https://gladiator.tf/sales?item=Strange+Australium+Grenade+Launcher or for average of 22.2 keys in past 7 days

el mostacho i bought for 26.03 € on skinport / 1.8 € (price of key on said site , its not stabel there ) so ~14 keys and there was 1 sale in past 30 days on gladiator.tf with ~15.6 keys https://gladiator.tf/sales?item=Twisted+Radiance+El+Mostacho

Now you can sell Strange Australium Grenade Launcher to bots on classified bp.tf 22 keys and 4.55 ref atm or lets just say ~22 keys. https://backpack.tf/stats/Strange/Australium%20Grenade%20Launcher/Tradable/Craftable

You can also sell Twisted Radiance El Mostacho for 16 keys 13.44 ref or ~16.24 keys

https://backpack.tf/stats/Unusual/El%20Mostacho/Tradable/Craftable/130

Now last two prices are for what you can sell them instantly so i understand they have no value until we sell items for that price but i like to think they are bear minimum

So prices for Strange Australium Grenade Launcher should be 21.5-22.5 keys (with over 20 bought/sold) - gladiator.tf stats

and for el mostacho i would say 14 - 16 keys - if needed i can show proof of transaction.

So the REAL price should be 300 keys pure + ~15 key unusual and ~22 key Australium Grenade Launcher = 335-338.5 // I simplified prices of unusual and strange australium but used mini/max prices in the end price of unusual Viridescent Peeper Patriot Peak
