American Armed Forces PX Cardboard Tokens (Pogs) as used in Afghanistan. These "coins" are money, just like ordinary nickels, dimes and quarters in America. But, unlike regular coins in America, they are not legal tender. Printing currency is against the law so AAFES (Army Air Force Exchange Services, the WalMart for the military) at the direction of the Department of Defense created these as "gift certificates" for use by service members participating in Operations Enduring Freedom and Iraqi Freedom. They are commonly referred to as "pogs." They were used in the place of coins in operational theatres.
