On 30 June 2011, when the25 paisa and all other lower denomination coins were officiallydemonetised, the 50 paise coin became the lowest circulating denomination of the Indian rupee.[1]
Prior to 1957, theIndian rupee was notdecimalised. From 1835 to 1957, the rupee was divided into 16annas. Each anna was further divided into fourIndian paises (pice) and each paise into threepies till 1947 when the pie was demonetised. In 1955, theParliament of India amended the "Indian Coinage Act" to adopt the decimal system for coinage. Paisa coins were introduced in 1957, but from 1957 to 1964 the coin was called "Naya Paisa" (English:New Paisa). On 1 June 1964, the term "Naya" was dropped and the denomination was simply called "One paisa". Paisa coins were issued as a part of "The Decimal Series".[2][3][4] In 2019, new coins were adopted, but the 50 paise coins were not updated as they have ceased to be in common circulation.[citation needed]
