a supernote is a counterfeit hundred dollar bill of exceptionally high quality. Supernotes are different from common fakes because they are printed on an intaglio press, which gives them the "relief" quality typical of real dollars. Detected in 1989, they make up a small portion of the mass of forged US currency currently circulating.
Supernotes also feature most of the well-known markers of real dollars, such as the plastic security thread, the watermark, and the red and blue security fibers.

The US Government and Interpol believe the supernotes to be of Northern Korean origin. The government of North Korea denies involvement. Some people are not convinced that North Korea could acquire all the necessary materials and technologies to produce such a convincing fake.
