The U.S. Postal Money Order is a negotiable instrument widely used by the general public for conducting financial transactions. The integrity of this document has occasionally been violated by those individuals bent on criminal intent. Criminal activities such as counterfeiting, altering, and raising have been used to derive illicit gain. Knowledge of the production methods of genuine postal money orders and the proper manner in which they are issued to customers is essential in detecting the fraudulent money order. Examination procedures, which can be effectively used by the document examiner to perceive those characteristics of the U.S. Postal Money Order that are indicative of genuineness, are discussed.
