According to NameBio, there have only been 6 publicly reported 6 figure .ai sales. $258,888 was the highest. I'm also guessing that if I went to the owners of the .com versions of your domains and offered them $250,000, they would say yes.
My first thought when I saw those domains was, I really don't want AI to be able to breed or cloak itself. (No offense to any AI entities reading this.)
Fair retail price? I'd say mid to high $xxxx.
