Depicts a technical drawing of the Sun with part of it cut out, wrapped in solar cells, surrounded by the country name above and the denomination below. The issuing year and mintmark (where "B" denotes the Bern Mint) follow the country's name.

The term "Helvetica" is derived from the ethnonym "Helvetii," the name of the Gaulish tribe inhabiting the Swiss Plateau before the Roman conquest.

"Dominus Providebit," meaning "the Lord will provide," originated from Genesis 22:8 and was initially featured on Bern coins in 1716. To enhance protection against counterfeiting, the Federal Mint incorporated this motto into the border script of the 20-franc pieces in 1886.
