Overview
India’s circulation coins are produced at four government-owned minting facilities located in Mumbai, Kolkata, Hyderabad, and Noida. These mints operate under the Security Printing and Minting Corporation of India Limited (SPMCIL), a Government of India enterprise established in 2006 to manage the country’s currency printing presses, mints, and security document facilities.
The mints manufacture coins required for circulation across the country as well as commemorative coins issued on special occasions. In addition to coin striking, several mints also produce coin blanks, medals, and other numismatic items. Modern minting operations rely on automated presses, metal refining systems, and quality control procedures to ensure consistent coin production.
Role in Coin Production
Under the provisions of the Coinage Act, the Government of India is responsible for the minting and supply of coins used in circulation. The Reserve Bank of India places annual requirements for coins, after which production schedules are planned across the four government mints.
The facilities at Mumbai, Kolkata, and Hyderabad also manufacture coin blanks and have metal refining and assaying capabilities. Some mints are equipped for producing commemorative coins and medallions, which are often issued to mark national events, anniversaries, and notable personalities.
Mint Details
Mumbai (Bombay) Mint
The Mumbai Mint is among the oldest minting institutions in India, with origins dating back to the late seventeenth century. One of the earliest minting operations in the city was established under Governor Gerald Aungier, and rupees were reportedly struck in Mumbai as early as 1672. These early coins were produced within the Bombay Castle area, near the present-day site of INS Angre.
The present mint complex was constructed between 1824 and 1830 under the supervision of Captain John Hawkins of the Bombay Engineers. When the facility began operations, mechanized equipment powered by steam engines enabled the mint to produce large numbers of coins daily, marking an important step in the modernization of coin production in India.
During the nineteenth century the mint was initially administered by the Bombay Presidency, but control was transferred to the Government of India in 1876. In the early twentieth century a branch of the Royal Mint of London briefly operated at the site, producing British gold sovereigns for circulation before closing in 1919.
Over time the mint expanded its activities beyond coin striking. Precious-metal refining facilities were introduced in the twentieth century, including gold and silver refining operations. The mint also began producing commemorative coins in 1964, the first issue honouring Jawaharlal Nehru.
Today the Mumbai Mint continues to play an important role in India’s coinage system, contributing to the production of circulation coins, commemorative issues, and precious-metal refining within the country’s minting network.

Kolkata (Calcutta) Mint
The Kolkata Mint has one of the longest histories among Indian minting institutions. Minting activity in the region began in the eighteenth century during the period of the East India Company. Early facilities were established to produce coins for commercial use in Bengal and nearby territories.
A purpose-built mint building was constructed in the early nineteenth century, with large-scale production beginning around the late 1820s. The mint manufactured coins in precious metals such as gold and silver as well as copper coinage used in everyday circulation.
Over time the mint expanded its capabilities to include the production of medals, decorations, and commemorative coinage. A newer mint complex was later developed at Alipore in the mid-twentieth century to support increasing demand for coin production in independent India.
Today the Kolkata Mint continues to produce circulation coins and commemorative issues and remains an important centre for the manufacture of official medals and decorations.
Hyderabad Mint
Minting operations in Hyderabad date back to the early nineteenth century during the rule of the Nizam of Hyderabad. Coins were originally produced for the princely state using locally established minting facilities.
After the integration of Hyderabad into the Indian Union in 1948, the mint came under the administration of the Government of India in 1950. Production gradually expanded to include coinage for national circulation.
A modern mint complex was later established at Cherlapally near Hyderabad in the late twentieth century. Equipped with advanced machinery and automated presses, this facility significantly increased the production capacity for both coins and coin blanks.
The Hyderabad Mint now plays a major role in supplying circulation coins for India and also operates refining and metal-processing facilities used in minting operations.
Noida Mint
The Noida Mint is one of the most modern minting facilities in India. It began operations in the late 1980s and was designed with advanced production technology to meet the growing demand for circulation coins.
This mint introduced large-scale minting of stainless-steel coins in India, marking an important development in the materials used for modern Indian coinage.
The facility is equipped with high-speed coining presses and automated production lines capable of manufacturing large quantities of coins and coin blanks. In addition to producing coins for domestic circulation, the mint has also struck coins for foreign governments.
Today the Noida Mint forms a key part of India’s minting network and contributes significantly to the country’s overall coin production capacity.
