Bundes Republik (Deutschland) coins are German 5-mark and 10-mark commemorative pieces. They were first issued in the 1960s and have continued to be distributed through recent years, according to CoinQuest.com. Except for coins issued before 1965, they are worth small amounts today, typically between $1 and $10.
Both the former East Germany and West Germany issued the coins, each featuring many different designs. The East German coins were known as coming from the Demokratische Republik. Some were issued in silver while others had elegant packaging. East Germany also issued some 20-mark pieces in addition to those of 5-mark and 10-mark value.
