Historic German Gold coins are popular among collectors of World Gold. In 1876 the German Mark became the only legal tender coin in Germany. Later, the German Mark was actually named the “Goldmark” in order to distinguish it from the Papiermark (papermark). The Papiermark was the noted papermark that suffered massive loss after World War I due to hyperinflation (you have likely seen the wheelbarrows full of them in photographs as they lost value.) In 1915 German gold coin production ceased completely. These historic Gold coins are popular among collectors of world Gold as they come from Prussia.
The German Marks allow collectors to purchase gold in smaller than 1 oz weights, but at higher premiums than standard bullion. Due to their historical relevance and lower mintages they are sought after by World Gold coin collectors.
