Conservative estimation based on the fact that a quicksell bot is selling normal stormy well wrapped hat for 80 and those bots usually undercut by quite a bit, which leads me to believe normal one could be maybe in the 90-100 realm. Considering only other stormy strange well wrapped hat is selling for 200, and other strange well wrapped hats are selling for well over double suggested value, for example strange burning flames selling for 666 with valuation of 300, I think 140 is a reasonable figure for the strange stormy well wrapped hat.
