Swiss Confederation, 20 Rappen 1968

The 20-rappens piece was first minted in 1850. It was made from billon, an alloy with a minimal amount of silver. In 1881 the metal was changed to pure nickel. At the same time the motif was changed. Since then, to 20-rappens coins bear the image of Libertas, and not of Helvetia, as is often assumed.
