About Iranian rial (IQD)
The Iranian rial is the primary currency used in Iran. The first use of the Iranian rial dates back to 1798. However, in 1825, the rial was discontinued and the country started using the qiran. Eventually, in 1923, Iran went back to using the rial, but as an updated currency. Iran has used the second Iranian rial as its national currency ever since.
Although Iranian currency is always exchanged and written in the rial, most Iranians refer to the value of money and the prices of goods in 'tomans'. A 'toman' used to be an official currency in Iran, but is no longer used. One toman is equal to the value of 10 rials.
