This is a bit fast but this hat was recently sold by me for a burning flames dr's dapper topper along with a Damascus and mahogany knife field tested with the unusual effect of hot. The burning flames dr's dapper topper is currently worth 220-250 keys (3 mo ago) with the lowest seller of 200 keys on market place followed by a 210 keys seller asking for pure. (https://backpack.tf/stats/Unusual/Dr%27s%20Dapper%20Topper/Tradable/Craftable/13) The Damascus and mahogany knife is unpriced but similar knives like the FT blitzkrieg knife with the unusual effect of hot is worth 32-40 keys (https://backpack.tf/stats/Unusual/Blitzkrieg%20%7C%20Knife%20%28Field-Tested%29/Tradable/Craftable/701). Seeing this skin knife is unpriced I will consider it at around 30 keys. The items added together is around 230-240 keys along with previous trades involving this hat (details in previous suggestion) of 165 pure and 215 in unuausl overpay, I will average them out to 190 keys (since i payed pure i will round it down)
