So there's a suggestion already out there for this but I don't think it will be done justice based on how that's going so I'm going to submit this for a more accurate price. 9 on the market nice hat, shitty effect.

link above bought from this guy for all the items in the bills trade 3 white bills, 1ts paint, last breath (check the item histories), ~1.4ish

This doesn't look like it's attracting anything >1.7 and the 1.6 QS guy has had no bites it seems, though I can't tell how long he's being quickselling. So 1.7 is the high end by that and the brigade if the seller adds which was c/o'd (trying to be conservative here). The low end comes from the 1.3 offers being rejected across the board and the 1.4 offer being consdered
