₹1 was equal to 64 paisa in 1947
When India became independent in August 1947, ₹1 was divided into 64 paise or 16 annas, with each anna being equal to 4 paisa. Under the Indian Coinage Act 'naya paisa' (new paisa) was introduced in 1957, with the rupee comprising 100 naya paise instead of 64 old paise. The rupee, however, remained unchanged in value and nomenclature.
