The design of German banknotes remained unchanged during the 1960s, 1970s and 1980s. During this period, forgery technology made significant advances so, in the late 1980s, the Bundesbank decided to issue a new series of Deutsche Mark banknotes. The colours for each denomination remained unchanged from the previous series but the designs underwent significant changes and a 200 DM denomination was introduced. Famous national artists and scientists were chosen to be portrayed on the new banknotes. Male and female artists were chosen in equal numbers. The buildings in the background of the notes' obverses had a close relationship to the person displayed (. place of birth, place of death, place of work), as well as the second background picture (Lyra and the musician Schumann). The reverses of the notes refer to the work of the person on the obverse.
Starting with the 1 Pf. in 1960, followed by the 10 Pf. in 1963, and the 5 Pf. in 1968, the old style coins were gradually replaced with new coins depicting the state name "Deutsche Demokratische Republik." Aluminium 1 Mark, 2 Mark and 50 Pfennig pieces were released for circulation in 1956, 1957 and 1958, respectively. In 1969, brass 20 Pfennig coins were introduced, with nickel-bronze (later cupro-nickel) 5 Mark coins issued from 1968. In 1973 and 1974, 1 and 2 Mark coins were redesigned dropping the former "Deutsche Mark" title. The brass 20 Pfennig coins were issued partly because pay telephones had a standard charge of 20 Pf. and were having problems with smaller aluminium coins jamming due to their light weight. Commemorative 5, 10, and 20 Mark coins of various types have also occasionally made it into circulation.
