I'm watching Secret Service Files Battlefront Colombia where they talk about the war on counterfeit currency and how its difficult to create fake US banknotes, but then they describe every single detail of a US banknote, from the colors used, the type of paper, the red and blue fibers within, the cotton and linen combination that create the distinctive feel, the fluorescent thread printed with microscopic text etc etc. And also how the $5 can be bleached and turned into $100 with "a little bleach and some ink". What a bunch of idiots I swear.
