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.
Many Germans have begun to modify their eating habits to lower their calorie and cholesterol intake. Since the unification of East and West Germany in the 1990s, the government has faced the challenge of bringing the living conditions in the former East Germany up to the standard found in the former West Germany. Upgrading housing, schools, and utilities will continue after 2001. Despite unequal living conditions, Germans in all parts of the country are well nourished. In fact, most German children have enough to eat.
