500 Kurush - Mehmed V Edirne

Mehmed V was a largely ceremonial ruler installed by the Committee of Union and Progress following the 1909 deposition of Abdülhamid II, and the high-denomination gold coinage of his reign reflects the Young Turk government's need to project fiscal stability after a constitutional revolution that had severely rattled foreign creditors. The 500 Kurush was effectively a presentation or treasury piece — too valuable for ordinary commerce, it functioned primarily in large state transactions and diplomatic contexts.

The Edirne mint attribution distinguishes this from the Constantinople issues. Edirne's output was considerably smaller, and high-denomination gold from that facility surfaces rarely in any grade.
