What is the value of a 1984 Bundesrepublik Deutschland 10 pfennig coin?

Answer 1

Please check your coin's date again and post a new, separate question. Rentenpfennigs carrying the name "Deutches Reich" were issued during the mid-1920s.

All German coins from 1950 to 2001 were simply deutschmarks and pfennigs, and were issued by the Federal Republic of Germany (Budesrepublik Deutschland).

Answer 2

This was an extremely common circulation coin until 2002 when Germany switched to euros. At that time it was worth about 5¢ in US currency. It has no added value as a collectible except in uncirculated condition, in which case it might sell for all of 30 cents.

Answer 4

The "1994" 10 Rentenpfennig coin is simply a 1924 one where the "2" got worn down and looks like a "9".

This happens because the German mint at the time used a weird font for it's dates.
