Swiss Confederation, 10 Francs (5th Banknote Series, in Circulation 1956-1980)

Until the 1950s, Swiss banknotes showed no security features whatsoever. But in 1956 new banknotes were put into circulation, which were produced on the latest security levels they were printed on fluorescent paper. For the first time, a 10-franc note was issued then the purchasing power of the Swiss franc had declined to a level that made it appropriate to offer a new denomination. The Swiss poet Gottfried Keller is shown on the obverse of this note. The reverse depicts a typical Swiss mountain plant, the creeping avens. The illustration was designed by the graphic artist Hermann Eidenbenz.
