Every Swiss coin struck since 1906 has come out of the same red brick building on the edge of Bern’s museum district. On 17 September 2026 that building stopped being the source and became the subject, and the Swissmint building gold coin, 4,000 pieces of 900 gold in proof, was showing as sold out in the Swissmint shop within days of going on sale.
Swissmint set the issue price at CHF 1,265 and capped the mintage at 4,000, a step down from the 5,000 that recent 50 franc gold issues have carried. Subscribers were covered automatically. Everyone else had a window that opened at 08:00 on a Wednesday morning, and the shop listing tells you how that went.
The mint makes itself the motif
Swissmint has been striking special coins since 1936, and the brief has always pointed outward: national events, cultural anniversaries, institutions, prominent figures. Shooting federations. Glaciers. Cable cars. Lakes.
This time the mint turned the camera around. The occasion is the 120th anniversary of the building at Bernastrasse in the Kirchenfeld district, the workshop that every modern Swiss coin has passed through, and the design does not treat it as background. It treats it as the portrait.
A classic federal building in Kirchenfeld
The building went up between 1903 and 1906 to plans by the Bernese architect Theodor Gohl, in a Neo-Renaissance style that was doing two jobs at once. Light red brick, cornices, decorative elements in natural stone: a prestigious industrial building of the early 20th century, according to Swissmint, with the functional demands of a mint underneath and the imposing face of a federal institution on top.
The new mint opened its doors in May 1906. On 2 July of the same year the entire Federal Council came to visit and formally took possession of it. Swiss coins had been produced in the country since 1855, and from that summer they were produced here.
4.35 square centimetres of façade
The obverse gives the façade a surface of just 4.35 cm², and the design spends all of it. In the centre sits the entrance portal, flanked by the half columns and pilasters of the central avant corps, with the segmental arch crowning the heraldic cartouche and its Swiss cross above. To either side of the main entrance are the two relief medallions by the sculptor Giuseppe Chiattone, reproduced small enough that most buyers will need a loupe to find them and large enough that they are unmistakably there.
The more interesting decision is in the finishes. Swissmint used a range of matte textures to stand in for the actual building materials, Saint Triphon marble, Bernese sandstone, klinker and sandstone from St. Margrethen. On a silver coin that job would go to colour. Here it goes to surface, which is the harder route and the one that survives being photographed badly.
A mosaic floor, reproduced in relief
The reverse stays indoors. At its centre is a coat of arms bearing the Swiss cross, its design taken from the mosaic floor at the foot of the building’s main staircase, one of the architectural features visitors see on a Swissmint tour. Around the edge run the face value of CHF 50, the inscription CONFOEDERATIO HELVETICA, the year 2026 and the mintmark B for Bern.
The edge carries DOMINUS PROVIDEBIT, the traditional Swiss gold inscription. It appears in the federal press release rather than on the Swissmint product page, which is worth knowing if you are cataloguing from the product listing alone.
Where the Swissmint building gold coin went
Swissmint issues two gold special coins in a normal year, and recent 50 franc issues have tended to disappear quickly, especially when they are tied to an event. The 2024 coin for the 200th anniversary of the Swiss Shooting Sport Federation ran to 5,000 pieces. So did the 2015 Aventicum issue. At 4,000, this one is deliberately tighter, and the anniversary it marks belongs to the issuer rather than to a federation with 130,000 members to sell into.
That combination did what it was always going to do. The coin went on sale at 08:00 on 17 September, and by 19 September the Swissmint shop was showing it sold out, with no proof units remaining outside the subscription.
The issue price is also worth a note. The 2024 gold 50 franc launched at CHF 799. This one launched at CHF 1,265 for the same 11.29 g of 900 gold, which tells you less about Swissmint’s pricing policy than about what has happened to the metal in two years.

What it leaves behind
Mints commemorate other people’s history for a living, and they are usually careful not to commemorate their own. This one made an exception, and the result is a small, dense, unusually self aware piece of work: a gold coin that shows you the room the gold coins come from. Four thousand collectors now own a miniature of a building that most of them will never walk into, struck inside the building itself. The tour is still the better way to see the staircase. For everyone else, there is now a 25 mm version, and as of this week it is already someone else’s to sell.
Frequently asked questions
What is the 120 Years of the Swissmint building gold coin? It is a 50 franc Swiss special coin issued on 17 September 2026 to mark the 120th anniversary of Swissmint’s headquarters in Bern. It is struck in gold 900, weighs 11.29 g, measures 25 mm and was released in proof quality only, in a presentation case. The obverse shows the façade of the building and the reverse carries a Swiss cross coat of arms taken from the mosaic floor inside.
How many were struck? 4,000 pieces, all in proof quality. That is below the 5,000 piece mintage carried by other recent Swissmint 50 franc gold issues, including the 2024 coin for the 200th anniversary of the Swiss Shooting Sport Federation.
What did it cost? Swissmint set the issue price at CHF 1,265, presentation case included. Holders of a Swissmint special coin subscription received it automatically at that price instead of competing for it in the online shop.
Can I still buy one from Swissmint? No. The Swissmint shop listing for article number 510000971 was showing the coin as sold out within days of the 17 September launch. Anything available now is coming from the secondary market or from a dealer who bought at issue.
How much gold is actually in it? The coin is struck in gold 900, so 90 percent of its 11.29 g is fine gold, roughly 10.16 g. The balance is copper. Swissmint uses this traditional alloy on its gold special coins rather than a 0.999 fine format, which is the same standard the historic Vreneli carried.
What does DOMINUS PROVIDEBIT on the edge mean? It is Latin for “The Lord will provide”, a phrase that has run along the edges of Swiss coinage since the 19th century. The federal press release for this issue confirms it on the edge, though the Swissmint product page does not mention it.
Is it legal tender? Yes. Swiss special coins carry an official, state guaranteed face value, and this one is denominated at 50 francs. Nobody is going to spend a coin that sold for 25 times its face value, but the denomination is real.
Why did Swissmint put its own building on a coin? Swissmint has struck special coins since 1936 to mark events, institutions and figures of national significance. In 2026 the 120th anniversary of its own headquarters supplied the occasion, and the design treats the building as the subject rather than as the place the coin happened to be made.
