Money
The Iranian rial (IRR) is the currency of Iran. It is issued by the Central Bank of the Islamic Republic of Iran. 100 dinar makes up a Rial; however, Dinars are not used in accounting because of the very low value of the Rial. Coins are issued in values of 50, 100, 250, 500, 1, 000, 2, 000, and 5, 000 rials. Banknotes are produced in 500, 1, 000, 2, 000, 5, 000, 10, 000, 20, 000, 50, 000, and 100, 000 denominations.
PS: Although the "toman" is no longer an official unit of Iranian currency, Iranians commonly express amounts of money and prices of goods in "tomans". For this purpose, one "toman" equals 10 rials.
