The rial (in Persian: ریال; ISO 4217 code IRR) is the currency of Iran and as of 2014 remains the world’s least valued currency unit.The name derives from the Spanish real which was for several centuries the currency in Spain (derived from Latin regalis [regal]).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.
