The obverse of the smallest gold coin in the world 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 Swiss francs together with the inscription "Helvetia" and the Swiss cross, supplemented by the alloy mark "AU 999.9" and the weight (1/500 ounce). Because neither image on the minted sides can be discerned with the naked eye, Swissmint has commissioned special packaging complete with magnifying lenses and light, ensuring that one can examine the smallest gold coin while still keeping it safely stored.
