1 Gulden - William I

Württemberg adopted the South German Gulden standard in 1825 through the Munich Coinage Treaty of that same year, which brought Bavaria, Württemberg, Baden, and several smaller states into monetary alignment at 24½ Gulden per Cologne mark of silver. This coin is a product of that treaty's first implementation year — one of the earliest Württemberg issues struck to the new standard rather than the old Kronentaler system William I had inherited.

The .750 fineness was a deliberate compromise, slightly below earlier conventions, to make the standard politically palatable to multiple treasuries simultaneously.
