Fals
The fals (plural fulus) was a copper coin produced by the Umayyad caliphate (661-750) and the Abbasid caliphate (750-1258) beginning in the late 7th century. The name is a corruption of follis, a Roman and later Byzantine copper coin. The fals usually featured ornate Arabic script on both sides. Various copper fals were produced until the 19th century. The word fulus is still used in modern spoken Arabic for money.
