Superdollar

A superdollar (also known as a superbill or supernote) is a very high quality counterfeit United States one hundred-dollar bill, alleged by the U.S. Government to have been made by an unknown organization or government. In 2011 government sources stated that these "counterfeit bills were in worldwide circulation from the late 1980s until at least July 2000" in an extradition court case. Various groups have been suspected of creating such notes, and international opinion on the origin of the notes varies. The U.S. Government believes that these notes were most likely produced in North Korea. Other possible sources claimed include criminal gangs in Iran, Russia, China or Syria. The name derives from the fact that the quality of the notes exceeds that of the originals. Some have estimated that 1 in 10,000 bills was a counterfeit of the quality ascribed to supernotes.
