It's believed that North Korea may have developed a way to create extremely good replicas of American $100 bills.

A number of fakes notes have turned up in neighboring South Korea whose quality is so high that they are virtually indistinguishable from the real thing.

It ended up taking a team of forgery specialists at the country's KEB Hana Bank to confirm that a single $100 bill found at a branch in Seoul in November was a fake.

The worry is now that there may be many more 'supernotes' that are now in circulation, but authorities simply have no idea.

Other fakes were dated either 2001 or 2003, but the new forgeries are dated 2006 and use even better techniques with more sophisticated ink, improved printing and paper.

Even features that are designed to stop fakes from being created have been incorporated into the forgeries that change colour when viewed from a different angle, just as genuine notes should.

The high quality of the forgeries has immediately led to suspicion falling on North Korea, which has a track record of forging foreign banknotes in order to earn hard currency for the regime.
