Money (which everybody wants) provides an intermediary substance, enabling the seller to choose when and where he wishes to become a buyer.
The earliest currency used in commercial transactions appears in Egypt and Mesopotamia by the third millennium BC. It consists of gold bars which need to be weighed to establish their value each time they are exchanged. Later they are supplemented by gold rings for smaller sums. In about 2500 BC an extensive trade, at Ebla in modern Syria, is based on currency of this kind in silver and gold.
The earliest known coins in the western world come from the city of Ephesus in Ionia (in western Turkey) in about 650 BC.
Many of the units of currency in use today derive from Roman originals, and more specifically from versions of the Roman coins minted during the Middle Ages.
