1/3 Thaler - John Frederick

Brandenburg-Ansbach came under the rule of John Frederick in 1667 following the death of his brother Albert, and his reign saw aggressive monetization partly driven by the costs of maintaining a court that consistently outspent its revenues. The 1/3 Thaler denomination — equivalent to 8 Groschen — gained traction across the fragmented German states in the 1670s as a practical intermediate denomination during a period when full Thalers were being hoarded and smaller coins were chronically debased.

John Frederick died in 1686 without legitimate heirs, triggering the reversion of Ansbach to the main Hohenzollern line in Berlin.
