10 things you probably didn’t know about Iran

Old habits die hard: Though Iran’s official currency is the Rial, you’ll soon notice that every time you fish for your wallet you’re being asked to pay in tomans. Don’t panic. You won’t need to go running back to the exchange desk. The toman was Iran’s old currency, replaced by the rial in 1932 at a rate of 1 = 10. So, when someone quotes a price to you in toman, all you have to do is times it by ten and you can start dishing out your rial bank notes.
