ElleKitty pretty much covered it... Just to add to that post...
1. 1975G 2Pfennig (J.381a) - (Bundesrepublik Deutschland) West Germany - Produced at Karlsruhe. 60,145,120 produced
2. 1949F 1 Pfennig (J.376) - (Bank Deutscher Länder) West Germany - Produced at Stuttgart (in the basement of the mint actually). 129,935,333 produced, but that coin may actually be worth a little bit. There were only two minting years, 1948 and 1949.
3. 1949G 5 Pfennig (J.377) - (Bank Deutscher Länder) West Germany under Allied Occupation - Produced at Karlsruhe, only one minting. 57,356,202 produced, the smalled of the mintings. Also could be worth something!
4. 1910A 10 Pfennig (J.13) - (Kaiserreich) German Empire - Produced at Berlin, 3,734,193 produced. Curiously, my reference values this lower than the Deutscher Länder coins! They were produced though, from 1890-1916.
5. 1921x 5 Pfennig (J.297) - (Kaiserreich/Weimar) German Empire - Whilst the 'Weimarer' era started in 1919, this coin design is a left over from the Kaiserreich era. The coin was produced from 1915-1922. Production figures were (A) 143,418,372 (D) 38,132,799 (E) 21,104,000 (F) 24,800,000 (G) 21,289,023 (J) 28,928,224. I dont know if its worth much...
