I don't have premium anymore, but I recall from when I did that the other three of these hadn't moved from the unboxers. If that's changed, please let me know or feel free to make a counter.

History for the Mostacho - https://backpack.tf/item/8168390609

This Mostacho specifically sold for $65 on November 8th, however with the abundance of sales at $40/45 since then, I'm taking the latter two as a key equivalent range. https://marketplace.tf/items/tf2/31074;5;u122

November 13th - 22 keys/$40USD

November 17th - 25 keys/$45USD

November 19th - 23 keys/$40USD

November 20th - 26 keys/$45USD

November 26th - 23 keys/$40USD

November 27th - 2x sales @ 23 keys/40USD

22-26 keys, 24 keys.

Sale #3 -

https://marketplace.tf/items/tf2/31041;5;u131

25USD/1.75 = 14 keys. I'm calling this a QS since I grabbed it pretty much as soon as it got listed, and it's only $5 above the current buy orders. If an admin feels it would be better to resuggest this with the wide range or even the lower value, feel free to tell me.

Have a good one!
