I recall reading somewhere that Tony Spilotro did something similar?
I don't know about leaving behind valuables but I think either Tony Spilotro said something to his loved ones like "If I'm not back by night, something very bad has happened."
Sonny Black is the one guy who was famous for leaving behind his jewelry and whatnot. They show Lefty doing this in the movie, but it was really Sonny Black if I remember right.
