10 Rupees FAO

Issued under the United Nations Food and Agriculture Organization coin program, which India participated in alongside dozens of other nations throughout the 1970s as part of a coordinated effort to raise awareness of the FAO's "Grow More Food" campaign. The Reserve Bank of India struck this piece in .500 silver — a deliberate departure from the cupro-nickel used for circulation coinage — positioning it as a collector and gift issue rather than everyday currency.

1973 placed this coin squarely within the period following India's Green Revolution, when wheat and rice yields had transformed dramatically due to high-yield variety seeds introduced in the late 1960s.
