Afghanistan - Set of 3 Notes - 10, 20 and 50 Afghan Afghanis - P-47, 48 and 49 - (1973) dated Foreign Paper Money

Set of 3 notes! 10, 20 and 50 Afghanis, P-47, 48 and 49. Security Strip on each. Front and back shown. The original afghani (ISO 4217 code: AFA) was introduced in 1923 during the era of King Amanullah Khan, replacing the Afghan rupee that was used since 1891. In addition to being subdivided into 100 puls, 20 afghanis were equal to one amani. The rate of conversion from the rupee is sometimes quoted as 1 afghani = 1 rupee 6 paisas, based on the silver contents of the last rupee coins and the first afghani coins. The afghani initially contained 9 grams of silver. Alongside the new currency, the various units of weight used in Afghanistan were replaced by a single metric system.
