The Austrian Mint has launched (22nd February) their latest coin in the silver niobium bimetallic series featuring Bionics, it is their tenth such coin to date. Bionics is the complex interdisciplinary field in which biological systems and evolution are applied in solving engineering problems and developing modern technology.
Designed by the Mint’s chief engraver Thomas Pesendorfer, the obverse of the coin is dominated by a cross section of the complex nautilus shell, often used as a model for leading edge modern design architecture. Above the nautilus is an eagle in flight – symbolizing the inspiration for an aircraft. The aircraft also has a special finish on the outer shell, which was based on sharkskin, which reduces friction and thereby allowing the aircraft to fly more efficiently. The lotus flower shown in the left center of the silver ring gave rise to repellents. The text “REPUBLIK OESTERREICH” (Republic of Austria) is positioned towards the lower right edge. The face value of the coin, 25 euros, is located to the upper right half of the pure niobium center disc and the year of issue “2012” is seen just below the denomination.
The reverse side of the coin shows an interior view of the Munich Olympic stadium, the roof of which was designed based on findings in the bionic world and on radiolarian shells. A highly magnified radiolarian shell is shown in the foreground. These shells normally have a size of .1 to .2 mm. Mint engraver Helmut Waehner designed the reverse side of the coin.
The new 25-euro coin is issued with a maximum mintage of 65,000 pieces and is struck in special uncirculated quality only. It has a diameter of 34 mm and contains 9 grams of .900 fine silver in the outer ring. The core consists of 7.15 grams of .998 pure niobium and has a striking bright pink color. Each coin is encapsulated, boxed and accompanied by a numbered certificate of authenticity.
