25 Rufiyaa FAO, Silver

Issued as part of the FAO's global coinage program, which recruited dozens of nations through the 1970s to mint commemoratives tied to food security themes — a campaign that flooded collector markets with low-mintage silver pieces from countries that rarely issued them otherwise. The Maldives participation was largely nominal; fishing, not agriculture, dominated the domestic economy, and the coins were distributed through international coin dealers rather than local circulation channels.

The .500 fineness is notably low for a commemorative silver issue of this period, a cost-driven choice made by several smaller FAO participant nations.
