Kuruş Coin: From Ottoman Empire to Republic of Turkey

Illustrated Specimen Details: Republic of Turkey 5 Kuruş

Example Specimen: 5 kuruş, 1925 — Republic of Turkey

Design & Inscriptions: The date on the coin is written as ١٣٤١ (1341) according to the Rumi calendar, which was officially used by the Ottoman Empire and the Republic of Turkey as its successor during 1839-1926. This corresponds to the year 1925 in the Gregorian calendar. The obverse features the denomination numeral ٥ (5) and the Arabic script قرش (kuruş), accompanied by a stalk of wheat.

The reverse proudly displays the star and crescent, the main elements of the state emblem of Turkey, positioned above an oak branch. The inscription reads جمهورية تركيا, meaning Republic of Turkey. This piece is a notable Mustafa Kemal Atatürk era coin. After the defeat of the Ottoman Empire in World War I (1918), Atatürk led the Turkish national revolutionary movement, creating a new republican state based on nationalism. He managed to carry out a number of decisive reforms quite quickly, including the elimination of the sultanate, the proclamation of the republic, the introduction of secular life (separation of religion from the state), clothing reforms, the Latinization of the alphabet (replacing the Arabic alphabet), and the introduction of the Gregorian calendar. Today, Turkey considers Atatürk its national hero.

2. OTTOMAN EMPIRE (17th-20th centuries): kuruş = 40 para = 120 akçe
3. CRIMEAN KHANATE (1777): kuruş = 8 beshlik

Etymology and History of the Kuruş

About the name of the coin kuruş (kurush): This Turkish term comes from the name of the old French coin "grossus denarius Turnosus" (gros tournois), which was very common in the Middle Ages. That is, kuruş has a similar etymology to a number of historical European coins, including the grosz, groschen, groten, grosso, garas, and groat. In turn, several other coins of the former territories of the Ottoman Empire got their name from the kuruş, such as the gersh and the qirsh. In Europe, another name for the kuruş was widely fixed — the piastre, leading to some uncertainty in numismatic catalogs where identical coin series are sometimes referred to as kuruş and other times as piastres. Additionally, the so-called new kuruş (yeni kuruş), temporarily minted in Turkey during 2005-2008, is sometimes considered a separate numismatic unit.

The Ottoman Empire and Monetary Context

The kuruş was one of the principal coin and currency denominations of the Ottoman Empire and later remained an important subdivision in several modern Middle Eastern and Balkan monetary systems. In the Ottoman era, 1 kuruş was equal to 40 para. The denomination became one of the central units of Ottoman currency from the late 17th century onward. It was introduced during a period of monetary reform, silver shortages, and significant economic transformation, gradually replacing older systems dominated by akçe silver coinage. The European influence on Mediterranean trade strongly affected Ottoman silver standards, denomination names, and their large-coin monetary structures.

Relationship with the Piastre and Modern Usage

In Western European numismatic terminology, the kuruş was often translated as the piastre. Consequently, many Ottoman and Middle Eastern coins described in European catalogs as piastres are locally known as kuruş or qirsh denominations. Today, the kuruş survives as the fractional subdivision in modern Turkey, where 1 Turkish lira equals 100 kuruş. Historically, the denomination also existed in Egypt, Syria, Lebanon, and former Ottoman territories in the Balkans under related forms such as qirsh, piastre, and gurush.

Physical Characteristics and Economic Role

Kuruş coinage historically appeared in silver, billon, copper, nickel, and modern alloys. Classic Ottoman issues commonly feature the elaborate tughra calligraphy of the sultan, Arabic-script inscriptions, and specific denomination and mint formulas. In contrast, modern Turkish kuruş coins feature the portrait of Mustafa Kemal Atatürk, national emblems, and modern Turkish inscriptions. Historically, the kuruş served as a principal Ottoman trade denomination, a major urban circulation currency, and a bridge between Ottoman and European monetary traditions.

Numismatic Appeal

Ottoman silver kuruş coins represent a major field of Islamic numismatics, with many debased and reform-era varieties available to study. Machine-struck 19th-century Ottoman kuruş pieces are especially popular among enthusiasts. Collectors place special value on large silver crown-sized issues, toughra-rich designs, and rare provincial mint varieties. Linguistically, the denomination perfectly illustrates the spread of the European groschen and grosz coin-name family directly into Ottoman Turkish monetary culture.
