5 Tomans / 50 000 Rials

Iran's redenomination law, passed in 2020, officially replaced the rial with the toman at a rate of 10,000:1 — a ratio that itself signals the scale of inflation the country had absorbed over the preceding decades. This note bridges the transition: the dual denomination printed on the face reflects the legal changeover period during which both units remained valid for quoting prices and settling transactions.

The toman is not new — it predates the rial by centuries and never left colloquial use. Iranians had been mentally dividing rial figures by ten in everyday speech for generations. The 2020 law simply made official what the public had been doing informally all along.
