Description

The India Government Mint, Kolkata was first established in 1757, and was located in a building next to the Black Hole in the old fort - where the GPO (General Post Office) stands today. It was called the Calcutta Mint and used to produce coins with the mint name, Murshidabad.

The second Calcutta Mint was established with the modern machinery brought in 1790 from England. It was located at the site of Gillet Ship building Establishment, which had been taken over by the Stamp and Stationary Committee in 1833. The coins issued from this mint continued to bear mint name Murshidabad.

In March 1824 the foundation of third Calcutta Mint was laid on Strand Road and was opened for production from 1 August 1829. Until 1835 the coins issued at this mint continued to be in the name of the Murshidabad Mint. The imposing frontage of the building of the third Mint was based on a design of the Temple of Athena in Athens, Greece, usually known as the Parthenon. The operative blocks were hidden out of view by the magnificent frontage.

This mint was named as "Old Silver Mint". The foundation for this mint was laid March 1824, and production began August 1, 1829.

The coinage production capacity then was varying between 3,00,000 to 6,00,000 pieces per day. In 1860 an annexe known as the "Copper Mint" was built to the north of the Silver Mint for the exclusive production of copper coins.

The silver and copper mints both used to function and produce coins of bronze, silver and gold. Both these mints were well equipped with the coining presses supplied by Boulton and Watt of Soho, Birmingham, England.

Apart from minting of coins another important function of the Kolkata Mint was the manufacturing of medals and decorations during the British regime. The production of medals continues to this day.

The Alipore Mint was opened on 19 March 1952. The full operation for the coinage and preparation of medals, decorations and badges started in Alipore Mint from this date. In addition to production of coins for domestic use also produces coins for other nations.
