The Fifty 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.
In regular circulation, the denomination is served by a banknote. These gold coins are non-circulating legal tender made for collectors and struck in proof grade only. They are issued in topical series, celebrating various aspects of Swiss heritage or nature. Swissmint has issued at least one every year since 2001. Initially, both sides of the coin carried a commemorative design; starting from 2004, the obverse is the same and only the reverse changes. (It is worth mentioning that some sources consider it the other way round, and call the commemorative part the obverse; however, we are going with the standard definition, which is that "obverse" is the side which specifies the issuing authority).
The edge is inscribed with the motto DOMINUS PROVIDEBIT (The Lord will provide - a quote from the Bible, Genesis 22, 8), and thirteen stars representing the original thirteen cantons of the Swiss Federation.
This coin commemorates the 100th Anniversary of Pro Juventute, a Swiss children’s and young persons’ organisation.
The Pro Juventute foundation campaigns in Switzerland for the needs and rights of children and young people with their parents. It helps in emergencies, offers social services in the areas of education, health and leisure activities, and fosters the personal development of children and young people. Among the means used by the Pro Juventute foundation to finance its activities are donations and the sale of postage stamps. It was originally established in 1912 with the aim of combating tuberculosis in children and young people. |
