1 Riyal / 100 Halalah - Khālid FAO

Issued under the FAO coin program, which ran from the late 1960s through the 1980s as a United Nations-backed initiative encouraging member states to mint coins with agricultural themes tied to development goals. Saudi Arabia's participation coincided with King Khālid's reign and the kingdom's third five-year development plan, which directed substantial oil revenues toward food security and rural infrastructure — a political priority made urgent by the country's near-total dependence on food imports at the time.

The FAO program produced hundreds of issues across dozens of nations, and collector interest varies sharply by country. Saudi issues from this window were struck in relatively modest quantities compared to the program's more prolific participants.
