Verification of the authenticity of United States currency, specifically the $100 denomination, involves a multi-faceted examination of its security features. This process ensures the bill has not been counterfeited. Examination includes scrutiny of the paper, printing quality, and presence of embedded security elements. For example, one would examine the security thread and watermark that are specific to genuine bills.
Ensuring currency is genuine prevents financial loss and supports the integrity of the monetary system. Historically, counterfeiting has undermined economies, making authentication procedures essential for maintaining public trust in currency. Verification methods have evolved alongside advancements in printing technology and anti-counterfeiting measures.
