75 Rupees 75th Foundation Day of ESIC

The Employees' State Insurance Corporation was established under the ESI Act of 1948, one of the first major pieces of social legislation passed after Independence, extending health and disability coverage to industrial workers. Commemorative rupee issues tied to institutional anniversaries have been a fixture of Indian numismatic policy since the 1960s, typically authorized through the Ministry of Finance under the Coinage Act.

The .500 fineness quaternary alloy used here is standard for Indian commemorative silver of this weight class — fine enough to qualify as silver coinage, inexpensive enough for broad institutional distribution.
