The Iranian Monetary Unit is the official currency of Iran. This currency has undergone various name changes, with its most recent being the Iranian Rial. However, there are other synonyms used to refer to the Iranian Monetary Unit, such as the Iranian currency, Iranian dinar, and Iranian toman. The dinar was the currency used before the Rial was introduced in 1932. On the other hand, the toman was the currency used in the Qajar dynasty and was revived in 2017. The toman is equivalent to ten Rials, making it easier for Iranians to understand and use in their daily transactions. Regardless of what it is called, the Iranian Monetary Unit is an essential part of the country's financial system and economy.
