These banknotes were issued by the German Reichskreditkasse (Reich Credit Bureau) and would circulate alongside the regular banknotes of the occupied country.
Coins and banknotes for circulation in the occupied territories during the war were issued by the Reichskreditkassen. Holed, zinc coins in 5 and 10 Reichspfennig denominations were struck in 1940 and 1941. Banknotes were issued between 1939 and 1945 in denominations of 50 Reichspfennig, 1, 2, 5, 20, and 50 Reichsmark. These served as legal tender alongside the currency of the occupied countries.
