||When soldiers were first sent to Afghanistan, there was a shortage of coins in the AAFES system, so small cost items such as candy were used as change. This system was not optimal, and AAFES wanted to make maximal use of their available shipping weight for goods for the soldiers and not use-up part of that weight to ship coins. It was suggested to use plasticized paper disc to act as an "IOU". This idea was developed and AAFES instituted the use discs, called "POGs", in the value of 5, 10, 25 cents. They are manufactured at the AAFES facility in Dallas.
