The Twenty 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 coins are non-circulating legal tender made for collectors. They are issued in topical series, celebrating various aspects of Swiss heritage or nature.
The edge is usually 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 features the Bernina Railway on the occasion of its 100th anniversary.
The Bernina railway line (German: Berninalinie; Italian: Linea del Bernina; Romansh: Lingia dal Bernina) is a single-track 1,000 mm gauge railway line forming part of the Rhaetian Railway (RhB). It links the spa resort of St. Moritz, in the canton of Graubünden, Switzerland, with the town of Tirano, in the Province of Sondrio, Italy, via the Bernina Pass. Reaching a height of 2,253 metres above sea level, it is the third highest railway crossing in Europe and the third-highest railway in Switzerland.
The line opened from 1908 in several sections; It was only on 5 July 1910 that the whole line could be opened, upon completion of the most difficult section between Bernina Suot and Poschiavo.
On 7 July 2008, the Bernina line and the Albula railway line, which also forms part of the RhB, were recorded in the list of UNESCO World Heritage Sites, under the name Rhaetian Railway in the Albula / Bernina Landscapes. The whole site is a cross-border joint Swiss-Italian heritage area. |
