UnDollars (UnMoney, Un$) are official money of UnMultiverse. They were created four score and ten thousand years ago to replace 426 other types of money. UnDollars can be used in every country/colony/circle/dimension/whatever of UnMultiverse. The value of UnDollars is regulated by the Undefeatables themselves. The currency is not subject to inflation or deflation because they're value is backed by the gods' will, which is the main reason everyone decided to use UnDollars (that and because the Undefeatables threatened them with death).
