The Decimal Series

The Decimal Series

The move towards decimalisation was afoot for over a century. However, it was in September, 1955 that the Indian Coinage Act was amended for the country to adopt a metric system for coinage. The Act came into force with effect from 1st April, 1957. The rupee remained unchanged in value and nomenclature. It, however, was now divided into 100 'Paisa' instead of 16 Annas or 64 Pice. For public recognition, the new decimal Paisa was termed 'Naya Paisa' till 1st June, 1964 when the term 'Naya' was dropped.

With commodity prices rising in the sixties, small denomination coins which were made of bronze, nickel-brass, cupro-nickel, and Aluminium-Bronze were gradually minted in Aluminium. This change commenced with the introduction of the new hexagonal 3 paise coin. A twenty paise coin was introduced in 1968 but did not gain much popularity.

Over a period of time, cost benefit considerations led to the gradual discontinuance of 1, 2 and 3 paise coins in the seventies; Stainless steel coinage of 10, 25 and 50 paise, was introduced in 1988 and of one rupee in 1992. The very considerable costs of managing note issues of Re 1, Rs 2, and Rs 5 led to the gradual coinisation of these denominations in the 1990s.
