I'm Going to Be the King of the World, Right?

If the U.S. broke up into some parts, what would those parts use for currency? Because if they use the dollar, in my opinion, they've accomplished nothing. States like Texas actually have a shitload of gold put away. Most other states don't. So I think that might have an input on what you would do. Florida has beaches and we're hot so maybe this is going to lead them toward independence.
