1/2 Thaler - Christian Frederick Charles Alexander 1/2 Konventionstaler

Brandenburg-Ansbach was one of the Hohenzollern's Franconian holdings, administered separately from Prussia but ruled by a cadet branch of the same dynasty. Christian Frederick Charles Alexander — Ansbach's last independent margrave — struck this half convention thaler under the Konventionsfuss standard established by the 1753 Austro-Bavarian monetary convention, which fixed the silver thaler at a specific weight relative to the Cologne mark and brought partial harmonization across the fragmented German monetary system.

Alexander abdicated in 1791, ceding Ansbach directly to Prussia and ending over three centuries of Hohenzollern rule in Franconia. Coins of his reign are the last independent issues from the margraviate.
