A dollar bill starts as a sheet of cotton-linen paper and ends up loaded with watermarks, security threads, holograms, and color-shifting inks designed to defeat counterfeiters. This film goes inside the United States Mint to watch coins struck from blanks of different metals depending on denomination, stamped with their designs under high-tech presses, then follows paper currency through the printing process where those anti-counterfeiting features get built in layer by layer. It traces money's history briefly, from bartering to coins to paper bills, before settling into the current system: a network of banks, the Treasury, and the Federal Reserve, which manages the money supply by setting interest rates and buying or selling bonds. The film also crosses into the criminal side of the story, showing how counterfeiters use increasingly sophisticated equipment to fake bills and talking to law enforcement about the effort to catch them. It stays close to process throughout, more concerned with machinery and materials than theory, aimed at anyone who has never thought past the cash in their wallet.
