IRR meaning in Country Currency ?

The rial (Persian: ریال ایران‎, romanized: riyâl-e Irân; sign: ﷼; code: IRR) is the currency of Iran.

There is no official symbol for the currency but the Iranian standard ISIRI 820 defined a symbol for use on typewriters (mentioning that it is an invention of the standards committee itself) and the two Iranian standards ISIRI 2900 and ISIRI 3342 define a character code to be used for it. The Unicode Standard has a compatibility character defined U+FDFC ﷼ RIAL SIGN (HTML ﷼).

The Iranian rial is currently the second weakest circulating currency in the world, as of May 2021, with one United States dollar equaling 42105.00 rial, only behind the Venezuelan bolívar where one United States dollar equals 2843332.39 bolívar.

A proposal has been agreed to by the Iranian parliament to drop four zeros, by replacing the rial with a new currency called the toman, the name of a previous Iranian currency, at the rate of one toman = 10,000 rials. This change is expected to take place between 2020 and 2022.
