Iranian currency (Rials) is going to be changed into Tomans.

Rial is the Iranian currency, but in daily life and for simple purchases, people use another currency named Toman. One Toman equals 10 Rials. In malls, grocery stores and other shops the prices on the goods are written in Rials but if you ask the seller, they will tell you the price in Tomans ( a tenth of the number shown on the price tag) that may cause confusion especially for the tourists. “Is this the currency with the extra zero or not?!” is a question usually asked by the tourists in Iran.
