A thaler () is one of the large silver coins minted in the states and territories of the Holy Roman Empire and the Habsburg monarchy during the Early Modern period. A thaler size silver coin has a diameter of about 40 mm and a weight of about 25 to 30 grams, or roughly 1 ounce. The word is shortened from Joachimsthaler, the original thaler coin minted in Joachimstal, Bohemia, from 1518.After the collapse of the Holy Roman Empire, the German Reichstaler survived in the form of the Prussian thaler (later Vereinsthaler) until 1871.
