On 24 January 1857, so-called confederation currency was agreed and introduced by Austria and the states associated in the German Confederation. This act ended the validity of the previous, conventional, currency. The base of the confederation currency was a pound of silver. In Austria, 45 gold Austrian coins were struck from the pound worth 30 tolars of the confederation currency. The validity of the confederation currency in Austria ended on 13 June 1867 when Austria withdrew from this mintage union after it lost war to Prussia. So-called “trading coins“ – gold crowns and half-crowns were struck as part of the confederation currency. Trading coins do not have a specific value in relation to the standard circulation coins, their real value is influenced by the market value of the precious metal contained in these coins.
