Star and crescent (left) surrounded by the country name "Republic of Turkey". Date below.

The star and crescent is an iconographic symbol used in various historical contexts but most well known today as a symbol of the former Ottoman Empire and, by popular extension, the Islamic world. The Republic of Turkey has no official national emblem, but the star and crescent (Turkish: ay-yıldız "crescent-star") design from the national flag is in use as de facto emblem, among other things printed on Turkish passports, on Turkish identity cards and diplomatic missions of Turkey.

Value within olive wreath.
