Until the 1920s, the currency of Afghanistan was the Afghan rupee, which was subdivided into paisa. In 1923, the rupee was replaced by afghani as its official currency.[2] One afghani is subdivided into 100 puls. At the time of introduction, a pul coin was made of copper and weighed one gram. However, a 10 pul coin weighed 6 grams.[3]
