20-franc silver special coin “4 Seasons – Winter” 2026 | 4 Seasons Series | Swissmint
On 22 October 2026, Swissmint will issue the new 20-franc special silver coin, “4 Seasons – Winter”. This special silver coin (fine silver 999) is the second in the four-part series “The 4 Seasons”.
In Switzerland, the four seasons are clearly distinct from one another. They divide the year into four periods, defined by astronomical, calendar or climatic characteristics. These four seasons result from the tilt of the Earth’s axis (approximately 23.5°) and the Earth’s orbit around the Sun. This alters the intensity, duration and angle of incidence of sunlight at a given location.
Obverse
In winter, the Northern Hemisphere is tilted away from the sun and therefore receives little light and heat. The snowflake symbolises this season in Switzerland. In the centre of the snowflake, a delicate world map centred on the Southern Hemisphere is depicted. Behind the snowflake is the Winter Hexagon, as seen in the southern winter sky. The coin’s edge bears the word “Enviern” (winter in Rhaeto-Romansh) as well as “december, schaner, favrer”, the Rhaeto-Romansh names for December, January and February.
Reverse
The four seasons are depicted on the face values of the “4 Seasons” series using a stylised vegetation cycle. The arid part of this vegetation cycle, representing winter, is raised and polished. Around the edge of the coin is the face value of CHF 20, the inscription “CONFOEDERATIO HELVETICA”, the minting year 2026 and the mint mark B for Swissmint.
The coin will be released in a limited issue comprising 8,000 coins in uncirculated quality in the blister and 3,500 coins in proof quality in presentation case. The proof silver coins are coloured in the shade typical of the season.
