The 5 kg copper bar from the edition Schloss Gldengossa is a unique product from GEIGER Edelmetalle. In addition to the traditional investment metals, copper is increasingly interesting. Unlike gold, the metal copper has a real consumption. The demand of copper is constantly rising worldwide. The reason is that more and more copper cable is used. Copper is also installed in modern technologies such as electric and hybrid vehicles. The increasing demand and rising costs for recycling of the metal show clearly that copper has a great potential as an investment metal. That's why we offer as one of the first dealers in Germany also copper bars in a practical form for investment. The bars have a fineness of 999/1000 and are separately foil sealed to protect them from tarnishing.
