Military Payment Certificates (MPC) were currency used to pay U.S. soldiers and other military personnel foreign countries. From 1946 until 1973 it was used one place or another. Starting a few months after WWII ended through after the end of the Vietnam . MPC was inexpensive but colorful banknotes. A total of fifteen series of MPCs were produced. Only 13 series were actually issued. The other two were destroyed, however some examples are known. Of the 13 released series a total of 94 different designs and denominations are known.Military Payment Certificates were issued in denominations of 5, 10, 25, and 50 cents, and in 1, 5, and 10 dollar, and starting in 1968 20 dollars. MPCs were convertible to U.S. dollars upon leaving a MPC zone, and convertible to local currency when going on leave. It was illegal for unauthorized personnel to possess MPC, and that policy, in theory, eliminated U.S. dollars from local economies.
