Heinrich Brüning
4 Reichspfennig coins were issued in 1932 as part of a failed attempt by the Reichskanzler Heinrich Brüning to reduce prices through use of 4 Reichspfennig pieces instead of 5 Reichspfennig coins. Known as the "Brüningtaler" or "Armer Heinrich" ("poor Heinrich"), they were demonetized the following year. See . The quality of the Reichsmark coins decreased more and more towards the end of World War II and misprints happened more frequently. This led to an increase in counterfeiting of money.
