Munich Coin Treaty
The Munich Coin Treaty of 1837 was a treaty agreed to by six southern German states which unified the currency of the states.
Agreed to on 25 August 1837, the six states agreed that the value of the gulden should be the same, regardless of which of the states issued it, and that the silver content on the gulden should be equal to 90 per cent of the coin's face value. The treaty also established that coins minted in any of the six states was legal tender in all six states.
The Munich Coin Treaty in part inspired the 1838 Dresden Coinage Convention, by which the Zollverein attempted to standardise its currencies. However, although the Dresden Convention standardised currency exchange rates, it did not make coins legal tender extraterritorially.
The Munich Coin Treaty was initially agreed to by Bavaria, Baden, Württemberg, Nassau, Hesse-Darmstadt, and the Free City of Frankfurt. Later, Hesse-Kassel and Hamburg also agreed to the treaty.
