Smallest gold coin in the world

With the new 1/4-franc gold, with a diameter of 2.96mm and weighing 0.063g, issued on 23 January 2020, Swissmint wanted to push boundaries, stretch the limits of technology and achieve something unique.

For the obverse of the smallest gold coin in the world, Swissmint drew inspiration from Albert Einstein, not least because of his determination and patience. From 1895 to 1914, Einstein lived mainly in Switzerland, where he also completed his studies in 1900, at today's ETH in Zurich. In 1901, he was granted Swiss citizenship and in 1902 he found permanent employment as a technical expert in the Patents Office in Bern. It was in 1905 that he published what is probably the most famous formula in the world: E=mc2.

The obverse of the smallest coin therefore features the famous image of Albert Einstein sticking out his tongue, and the year date 2020. The reverse shows the nominal value of 1/4 franc together with the inscription "Helvetia" and the Swiss cross, supplemented by the alloy mark "AU 999.9" and the weight (1/500 ounce).

It goes without saying that the smallest gold coin in the world comes in specially developed packaging. After all, neither image on the minted sides can be discerned with the naked eye. So Swissmint has commissioned special packaging complete with magnifying lenses and light, ensuring that you can examine the smallest gold coin while still keeping it safely stored.

The new 1/4-franc gold coin designed by Swissmint's engraver Remo Mascherini is available as 'special minting' in a presentation case at our online-shop or from selected coin dealers and banks.
