This is the inaugural issue in a new four-coin series called The Four 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.

In summer, the northern hemisphere is tilted most towards the sun and thus receives more light and heat during this season. The sun therefore features as the symbol of this season on the obverse of the coin. A world map centered on Switzerland is depicted in filigree at the heart of the radiant sun. At the bottom left is the constellation typical of summer, the “Summer Triangle”. Along the edge of the coin are the words “Estate” (summer in Italian), as well as “giugno, luglio, agosto”, the Italian names for the months of June, July and August.

The reverse features all the four seasons depicted on the “4 Seasons” series using a stylized vegetation cycle. For this issue, the section representing summer is raised and polished; the plant appears in full bloom.
