The Ten Francs coin is a denomination of the Swiss Franc. Given that Switzerland has four official languages, the Franc has three different names: Franken in German, franc in French and Romansh, and franco in Italian. Initially when federal Swiss coinage was introduced in 1850, all "francs" (including the half franc) were full-bodied silver, while the centimes were either billon (low-grade silver) or base metal.
The normal circulating 5 FR denomination was supplemented by circulating commemorative one-year type 5 Franc coins in silver and copper-nickel.
In 1999, Swissimint changed the concept and started striking non-circulating commemoratives for collectors only, which were bimetallic 5 Francs at first. After only six coins were issued in the first five years, this format was discontinued. Further non-circulating bimetallic coins are now denominated as 10 Francs, such as those listed below.
The 10 Francs are bimetallic and have the same dimensions as the bimetallic 5 Francs, but their colours are reversed: with an Aluminium Bronze outer ring (92% copper, 6% Aluminium, 2% Nickel) and a copper-nickel inner circle (75% copper, 25% nickel). They are issued in topical series, celebrating various aspects of Swiss heritage or nature.
The 2016 Ten Francs collector coin is dedicated to the Edelweiss flower. It is part of a small series on Alpine flora.
The obverse of the coin is common with the other commemorative 10 Francs and is designed by Roland Hirter; the reverse is designed by Jenny Leibundgut and features an edelweiss.
Leontopodium nivale, commonly called edelweiss, is a mountain flower belonging to the daisy or sunflower family Asteraceae. The plant prefers rocky limestone places at about 1,800 - 3,000 metres altitude. It is non-toxic and has been used in traditional medicine as a remedy against abdominal and respiratory diseases. It is a scarce, short-lived flower found in remote mountain areas and has been used as a symbol for alpinism, for rugged beauty and purity associated with the Alps and Carpathians, and as a national symbol, especially of Romania, Austria, Bulgaria, Slovenia, and Switzerland. According to folk tradition, giving this flower to a loved one is a promise of dedication.
Bimetallic 10 Franc coins are legal tender but are issued in small quantities for collectors only and do not circulate. |
