The Maria Theresa Thaler was originally struck in Austria between 1740 and 1780. It was the circulating currency of the Holy Roman Empire and its dominions and it was one of the most important trade coins in Europe and the world.
Since the death of Maria Theresa in 1780, the coin has always been dated 1780. It has been continuously minted in various mints around the world: Birmingham, Bombay, Brussels, London, Paris, Rome, and Utrecht, in addition to the Habsburg mints in Günzburg, Hall, Karlsburg, Kremnica, Milan, Prague, and Vienna.
