Have you ever noticed small symbols or stamps on U.S. dollar bills? These are called chop marks, used to show that a bill has been checked and verified as authentic.
Common in parts of Southeast Asia, Africa, and Latin America, chop marks originated in China, where merchants stamped silver coins to confirm authenticity and weight. Over time, the practice extended to paper money, including U.S. dollars circulating abroad.
Chop marks don’t reduce a bill’s value or functionality, though heavily marked bills may sometimes be rejected by banks or machines.
