Swissmint has announced the release of a new 20-franc silver “hydropower” coin, honouring the promotion of renewable energies and the sustainable use of resources. The fine coin is the first coin in Switzerland with coloured details and fluorescent elements that start to glow in the dark.
The new coin, designed by Swissmint's engraver Benjamin Löbbert, is available for purchase only in proof quality in a presentation case at Swissmint’s online-shop as well as from some coin dealers and banks.
