10 Tuman - Ahmad Qajar

Ahmad Shah ascended the Qajar throne as a child in 1909 after his father Mohammad Ali Shah was deposed and forced into Russian exile following a constitutional crisis. The 10 Tuman gold pieces struck under his name represent the largest denomination routinely issued by the Qajar monetary system, but Ahmad's government exercised increasingly nominal control over the mint as British and Russian spheres of influence divided the country under the 1907 Anglo-Russian Convention.

The Shah himself was abroad in Europe when Reza Khan's coup effectively ended Qajar rule in 1921, rendering these among the last gold issues of a dynasty that had governed Iran for over a century.
