Notwithstanding its appearance last November, I can find no alert, warning or public announcement, from any US regulator, or law enforcement agency, notifying the American financial community at large, about the new Series 2006 North Korean $100 "Supernote." This new counterfeit note, which was first seen in South Korea in 2017, reportedly defies easy identification as a fake.
Not only is the Supernote extremely difficult to recognize, its release comes at a time when North Korea is desperate for hard currency, due to international sanctions, and other factors, and if the Supernote is sold off, in bulk, to criminal elements, it could seriously damage America's image abroad, and cause widespread reluctance to accept ANY one hundred dollar bill, even those later than 2006, which have a host of additional anti-counterfeiting features.
Where is the US Secret Service in all of this ? That agency has primary responsibility in protecting the public from counterfeiting of US currency, and I understand that no examples of the new Supernote have yet to appear in the Continental United States, but this is an excellent time to alert the financial industry about the issue.
