Swissmint CHF 20 Silver Solar energy - Proof
With the 20-franc silver coin "Solar energy", issued on 21 July 2022, Swissmint is continuing the three-part "Energy of the future" series launched last year. As with last year's "Hydropower" commemorative coin, the fluorescent elements glow in the dark.
In addition to hydropower, the main sources of renewable energy in Switzerland are solar and wind power, although these two are only used to a very modest extent at present. The use of inexhaustible renewable energies should help to reduce dependence on oil, gas and nuclear technology, and, in the longer term, even help to phase out fossil energy supplies.
With its "Energy of the future" series, Swissmint wants to draw attention to the issues of climate change and renewable energies, which are important to us all.
The 20-franc silver coin with coloured details and fluorescent elements, designed by Swissmint's engravers Benjamin Löbbert (obverse) and Remo Mascherini (reverse), is available for purchase only in proof quality in a presentation case at our online-shop.
