Seventh banknote series, 1984
The banknotes of the seventh series were designed by Roger and Elisabeth Pfund, who had won the competition for the sixth series. However, as the SNB finally decided in favour of the designs by Ernst and Ursula Hiestand, Roger and Elisabeth Pfund were instead charged with designing the reserve series. These reserve banknotes were never put into circulation. The seventh series was the last reserve series. Rather than developing a new reserve series, the security features of the eighth series have been continually improved.
