100 Tomans / 1 000 000 Rials

Iran's chronic inflation made the rial increasingly impractical for everyday transactions long before this note appeared. By 2020, a single US dollar exchanged for well over 40,000 rials, and paying for groceries required fat stacks of smaller denominations. The 100 Toman / 1,000,000 Rial denomination — the highest face value ever circulated in Iran to that point — was a direct response, though it amounted to roughly two dollars at street rates when issued.

The dual naming reflects a law passed by the Iranian parliament in 2020 to officially redenominate the currency, replacing 10,000 rials with one "toman" on paper, though implementation lagged. This note effectively bridges the old and new systems mid-transition.
