The Indian rupee has had a long history of currency development from different regional issuances prior to independence to the modern standardized national currency. Key events include:
1) Regional presidencies issued different coinage until 1835 when a single East India Company coinage was introduced. This continued after British Crown control until 1862.
2) India's first paper money was issued in the 1860s and the Reserve Bank of India began production in 1938. New designs removed portraits of kings after independence.
3) Decimalization in 1957 introduced the naye paise, dropping "naye" in 1964. Coins transitioned from precious metals to base metals and new higher value coins were regularly introduced.
