New special coin issue: Swissmint's 120-year-old building depicted in gold

Bern, 15.09.2026 — On 17 September 2026, Swissmint will issue the new special coin “120 years of the Swissmint building”, which skilfully showcases the architectural highlights of this federal building in Bern.

Swissmint produces exclusive limited-edition collector coins under the name “Swiss special coins”. Swissmint is celebrating the 120th anniversary of the Swissmint building in style with the new 50-franc gold special coin.

A federal building in the Kirchenfeld district

The Swissmint building was built by Bernese architect Theodor Gohl in the Kirchenfeld district between 1903 and 1906, and is in the Neo-Renaissance style. After the new mint started operations in May 1906, the entire Federal Council visited the mint and officially took ownership of the building on 2 July 1906. It is located on the edge of Bern's museum district, and surprises visitors with a wealth of special architectural features, including the main staircase.

The special coins bring our country's history and memories to life

The new special coin “120 years of the Swissmint building” is made of a .900 gold alloy. This CHF 50 coin weighs 11.29g and has a diameter of 25mm.

The obverse, which has surface area of only 4.35cm2, shows the Swissmint building in all its glory: the imposing entrance gate, the half-columns and pilasters of the central avant-corps, and the crowning segmental arch above the cartouche featuring the Swiss cross. To the left and right of the main entrance, two relief medallions by Giuseppe Chiattone can be seen. The construction materials (St Triphon marble, Bernese sandstone, clinker and St Margarethen sandstone), which were in common use at that time, are depicted through different matt finishes.
