One Franc, CuproNickel, Coin Type from Switzerland - detailed information

The obverse, which has remained unchanged from 1875 to the present, features Helvetia standing on a platform, her head facing to the left. In her right hand (at the left), she holds a lance, and with her left (at the right), she props up a shield with the Swiss Cross at centre. In exergue is the legend HELVETIA.

On all coins made from 1875 to 1982, there are 22 five-pointed stars along the rim of the coin, going from the lower left to lower right boundaries of the obverse. These represent the 19 full Swiss cantons of the time and the six half-cantons, which are collectively represented by the three remaining stars. However, when the Canton of Jura broke away from Bern in 1979, the number of stars was no longer accurate. As a result, a new star was added to the right of Helvetia's likeness in 1983. On examples of all dates, the tip of Helvetia's lance extends to the rim and separates the ninth and tenth stars in the sequence. Nine of the stars are engraved up to the lance, two between the lance and Helvetia's face, and 11 or 12 to the right of the central allegorical figure, depending on the year of issue.

The engraver's signature, A.BOVY INCT. (an abbreviation for the Latin text "Antoine Bovy incidit", meaning "engraved by Antoine Bovy), is located around below, displayed counter-clockwise in small letters. It is split in two by the legend: "A.BOVY" appears to the left of "HELVETIA", and "INCT." to the right.

The reverse, which has remained unchanged since 1850, shows the value - a numeral 1, and a language-neutral abbreviation of the denomination, Fr., above the date: [year] within a wreath whose left part consists of oak branches and the right part of various Alpine flowers.

Below the ribbon of the wreath is the mint mark B of Swissmint (formerly known as the Bern Mint, then the Federal Mint of Switzerland), with the exception of the years between 1970 and 1985 (incl.) when there was no mint mark, and 15 mln coins dated 1968 which were struck by the Royal Mint.

One Franc coins were issued with coin alignment (opposite axis) until 1981, then with medal alignment (the two sides with the same axis).
