An article by Ursula Kampmann in the May 7, 2015 issue of CoinsWeekly describes a new anti-counterfeiting coinage technology
invented in Germany. -Editor
The narrow blue ring that separates the map of the earth on the center from the universe on
the surrounding ring on the new German commemorative coin “Planet Erde” (“Planet Earth”) is not made of metal but of a polymer. This
polymer is a little sensation within minting technology. It has been developed by a team that consisted not only of Dr Peter Huber
(Director of the State Mints of Baden-Wuerttemberg) and Günther Waadt (Director of the Bavarian State Mint) but also of representatives of
the German Central Bank, the European Vending Association and coin blanks producer Saxonia. The team brought in additional know-how from
the Leipniz Institute of RWTH Aachen University.
The fruit of this interdisciplinary collaboration is a polymer that can be coined and meets all requirements of a coin material: it is
both chemically resistant and resistant to heat and cold, UV radiation and water.
This unique polymer is not only beautiful to look at but can be applied as a new security feature. Thanks to this material, the very
first coins can now be produced that keep up with banknotes in terms of counterfeit prevention. Hence, the German mints have developed an
innovation which mints throughout the world are currently searching for. Improving the coins’ counterfeit prevention is considered a
prerequisite for raising the value limit between banknotes and coins. Today, this is what many central banks are aiming for. The reason is
quite simple: coins may be more expensive to produce than banknotes but they stay in circulation much longer. A lot of money could be
saved, if a banknote like the 5 euro note, for example, was replaced by a 5 euro coin.
This is now within reach even though the first 5 euro coin is a commemorative coin “only”. The Ministry of Finance wants “to capture the
interest especially of young target groups for German collector coins”.
Anyhow, this commemorative coin is not just a commemorative coin but a milestone in the development of minting technology.
