50 Lira FAO

Issued as part of the FAO's coordinated global coin program, which ran through the 1970s and recruited dozens of national mints to produce commemorative silver pieces tied to food security themes. Turkey's 1977 entry coincided with acute domestic economic pressure — the country was in the middle of a foreign currency crisis that would eventually force a major IMF intervention in 1978 and contributed to the political instability preceding the 1980 military coup.

The .830 silver standard used here reflects Ottoman-era fineness conventions that Turkish minting practice never fully abandoned.
