One Centime (Rappen) 1951, Coin from Switzerland - detailed information

The One Centime coin was the smallest circulating denomination of the Swiss Franc from its inception in 1850 until it was demonetised at the end of 2006. Given that Switzerland has four official languages, the sub-unit of the Franc has four different names; it is centime (c.) in French, Rappen (Rp.) in German, centesimo (ct.) in Italian and rap (rp.) in Romansh. Some English-language catalogues call the coin a "1 Rappen" coin, but the English-language publications of the Swiss National Bank and Swissmint prefer the word "1 centime".

Swissmint states that the first version of the coin was designed by Alexander Hutter and engraved by Jean-Jacques Barre of Monnaie de Paris (the Paris Mint), where Swiss coins were struck for the first couple of years after their introduction. This was used for almost a century until, in November 1947, the Swiss Federal Mint (now Swissmint) put out a call for new designs of the one and two centime coins, for which Josef Tannheimer won the first prize. Starting in 1948, these coins were minted with his designs, until they were discontinued in 2006 and 1974 respectively. Coins carrying the first design were demonetised on 1st February 1952.

The 1-centime coin was still produced until 2006, albeit in ever decreasing quantities, but its importance declined. Those who could justify the use of 1-centime coins for monetary purposes could obtain them at face value; any other user (such as collectors) had to pay an additional four centimes per coin to cover the production costs, which had exceeded the actual face value of the coin for many years. The coin fell into disuse in the late 1970s and early 1980s, but was only officially fully withdrawn from circulation and declared to be no longer legal tender on 1 January 2007.

Thus, coins issued in 1951 circulated for 55 years.
