100 Rupees Golden Jubilee - Reserve Bank of India

The Reserve Bank of India was established in 1935 under the Reserve Bank of India Act, and this 1985 issue marks exactly fifty years of its operation as the country's central monetary authority. The RBI launched as a privately owned institution before being nationalized in 1949, two years after independence — a distinction worth noting given that this jubilee coin celebrates an institution whose first decade operated entirely under colonial governance.

The .500 fineness reflects India's consistent policy through the 1980s of issuing commemorative silver at half-fineness rather than sterling, keeping production costs manageable during a period of tight foreign exchange reserves.
