The Persian currency consists of two main denominations: the Rial (4 letters) and the DINAR (5 letters). The Rial is the official currency of Iran and is subdivided into 100 smaller units called DINAR. The DINAR is a unit of currency used in some Middle Eastern countries, including Iraq and Kuwait. It is also sometimes used in other parts of the world, such as North Africa and the Indian subcontinent. Both the Rial and the DINAR are widely accepted in international trade.
