25 Kuruş

These small gold pieces were struck in the earliest years of the Turkish Republic, as Atatürk's government was actively dismantling Ottoman monetary structures and asserting a new national currency identity. The 1926–1929 window corresponds directly to the period when the Republic was consolidating its financial institutions, including the establishment of frameworks that would eventually produce the Central Bank in 1930.

The .917 fineness follows the standard established for Ottoman gold coinage and carried forward without alteration — a practical continuity beneath the ideological rupture of the new Republic.
