U.S. dollar

American Dollar ($): Also known as Dead Presidents, Prezzes, Leaves and Grass, the American dollar has changed little from that of the 20th century. It is a little harder to counterfeit, thanks to holograms, and is made out of a plastic that looks and feels like flanneled paper but is immune to most mundane methods of destruction (this cash you can wash, chombata). American dollars are less stable than before, prone to wild fluctuations due to inflation and the quirks of a credit-based economy. In such cases, the holder of a wad of dollar bills can be left holding a pile of junk. A junk that's hard to burn even! Oh well, it's only money, right?
