Reverse description	The reverse is dominated by a vignette of the main building of Gazi University in Ankara, an early Republican-era structure designed by architect Mimar Kemaleddin, rendered in fine-line intaglio engraving. To the left, a section of a historic Roman aqueduct is depicted, referencing Anatolia's architectural heritage. Geometric forms — a sphere, cube, and cylinder — appear as symbolic references to architectural design principles, set within a teal and olive-green guilloche background.
