Noble metals
Noble metals are metals that have a special protection against corrosion. For centuries, above all the gold and silver are fundamental elements in jewelry or coins minted. In the periodic table of the elements all noble metals are together on the right, in the so-called zone of transition metals.
There are further differentiations within noble metals. Thus, copper, silver and gold are also called “metal coin”. Platinum and Palladium, on the other hand, are part of the so-called “Platinum Group”. In addition to these known noble metals, in their group are also other elements, such as rhodium (Rh), ruthenium (Ru), osmium (Os), Iridium (Ir), mercury (Hg), bohrium (Bh), hassium (Hs), meitnerium (Mt), Darmstadtium (Ds), roentgenium (Rg) and copernicium (Cn).
High prices and places of exploitation
The high price of noble metals such as gold, silver, Platinum or Palladium is mostly result of its limited availability and also difficult to obtain through underground or open-pit. It is interesting that many noble metals can be found and obtained “together” in a same mining. This happens especially with the Palladium, osmium and ruthenium. Obtaining and exploitation are scattered all over the world. However the most important noble metals for the manufacture of coins and ingots, i.e. gold, silver, Platinum and Palladium, are mostly in South America, Australia and Africa. In the past there were also mines gold in Central Europe, as it was the case in Transylvania, Romania.
Coins of precious metals investment
For the manufacture of investment coins important noble metals are above all gold, silver and copper. Copper serves, for example, as complementary in alloy with gold element, so that the coins are more robust against mechanical actions. Also the Palladium and Platinum, the platinum group, presented a remarkable investment value and are used for the manufacture of coins and ingots.
For centuries men have felt a special attraction to the precious like gold and silver, perhaps due to its brightness or the scarcity of both elements. In addition to its use as a financial asset, these noble metals are used in the manufacture of jewelry and all kinds of luxury items. It could be argued that noble metals are a symbol of social status that reflects the prosperity of its owner. But do not forget the important role the noble metals in industry as raw materials and its application in the most varied economic goods: computers, chemicals and gold dental crowns are just a few of the many examples of their application.
