The first year West Germany issued coins at a national level following World War II was in 1950. At the time, billions of coins were minted and introduced as a way to help rejuvenate the country's lagging economy. There were so many coins minted that additional 10 pf. coins were not made again for 16 years, until 1966. The 1950 date on circulated coins was very common until 2002, when Germany adopted the euro.
According to Wikipedia, the inscription Bundesrepublik Deutschland (Federal Republic of Germany) appeared on the coins starting in 1950. These coins were issued in denominations of 1, 2, 5 and 10 pfennig. German coins include a mint mark, which indicates where the coin was produced. For example, the "D" indicates Munich, the "F" indicates Stuttgart, the "G" indicates Karlsruhe and the "J" indicates Hamburg. The coins were made with bronze, brass-plate, nickel and copper.
