Smilin Sam from Alabam

I have been investigating these machines and I hear of Cast Iron ones Cast Aluminum ones, some that have a coin slot that stands up off the head and some that are chrome and flat and say 1cent with x's across it and braded down to the head. Some that are described as 1970 ish and some 1930's. What's the story on these? Can someone help me out?
