On 29th April 2021, the Federal Mint Swissmint launches a new commemorative coin. “The Bridge of Life”, one of Sandro Del-Prete’s best-known works, adorns the silver coin.

The world of illusion is the artistic representation of impossible objects, optical illusions and double images. Various painters and artists use these optical techniques (trompe l’oeil) to create unusual and surprising effects for the observer in a bid to evoke amazement and astonishment.

Switzerland / 20 swiss-francs / silver .835 / 20.00g / 33 mm / Mintage: 20,000 (uncirculated), 5,000 (proof).

The Swiss artist Sandro Del-Prete from Hettiswil near Hindelbank is an important representative of drawings and objects involving optical illusions. The design on the 20-franc silver coin was based on his oil painting “The Bridge of Life”. Describing this work, he said: “The people are perpetually moving forward, towards the observer, and are never seen from behind. They are always heading towards the end of life. As no one gets younger as time passes, no one can be seen from behind either. This contains and illustrates one of the secrets of the universe: Where is the past? Where is the present? Where is the future?”


Attention, on the same day Swissmint issues a new gold coin dedicated to 50 years women’s vote in Switzerland.
