K1NG's Info:

Both unusuals in your DBD Cosa mini are outdated (and this was added there: https://backpack.tf/item/5370693627). Anyways, there are two sales on marketplace at around ~46:

https://marketplace.tf/items/459;5;u62

https://backpack.tf/item/1857579795

https://backpack.tf/classifieds?item=Cosa%20Nostra%20Cap&quality=5&tradable=1&craftable=1&australium=-1&particle=62&killstreak_tier=0 ----- unsold at 43 in classies

Taking 43-46 for it should be ok.

However, sale 3 had a B/O of 60:

So resuggest at 56-60.
