Currency notes and coins are the backbone of any country’s economy. In India, the production of banknotes and coins is a highly secure and regulated process managed by the Reserve Bank of India (RBI) and the Government of India. Have you ever wondered how many printing presses are responsible for producing currency notes? Or where coins are minted? Let’s explore the fascinating world of currency production in India.
The Role of the Reserve Bank of India in Currency Printing
The Reserve Bank of India (RBI) is responsible for managing and controlling the circulation of banknotes in the country. However, the actual printing of currency notes is carried out by specialized printing presses under strict security protocols. The RBI oversees the quantity, quality, and design of banknotes to ensure their authenticity and prevent counterfeiting.
