Known as the Brüningtaler or Armer Heinrich ("poor Heinrich"), they were demonetized the following year. See Brüningtaler . 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. Production of silver 1 ℛℳ coins ended in 1927. In 1933, nickel coins were introduced, and new silver and coins were introduced which were smaller but struck in .625 and .900 fineness so as to maintain the amount of silver. Between 1933 and 1939, a number of commemorative pieces were issued. Production of the coin ceased altogether. In 1935, aluminium 50 ℛ₰ coins were introduced, initially for just the one year. In 1937, nickel 50 ℛ₰ coins were issued and continued to be produced up to 1939, before reverting to aluminum. From 1936 on, all coins except the and the first version (1935–36) of the coin (bearing the image of the late president Paul von Hindenburg) bore the Nazi state insignia. The eagle had two standard designs on most coin denominations, a soaring eagle and large swastika depicted on most earlier issues, and a more 'aggressive' eagle with less prominent swastika which became predominant in the 1940s. During World War II, bronze and aluminium-bronze coins were replaced by zinc and aluminium, with the 2 ℛ₰ discontinued for potential of being too easily mistaken for the 5 ℛ₰ when struck in the same metal. The 1 ℛℳ, 2 ℛℳ, and 5 ℛℳ coins were no longer issued, replaced instead by banknotes. Aluminium 50 ℛ₰ coins were reintroduced to replace the nickel versions. This time around they had a longer run, being produced from 1939 to 1944. Lower denominations were produced in zinc from 1940 onwards. Due to their composition, these coins had poor durability and are hard to find in very good condition. The last production of coins bearing the swastika was in 1944 (1 ℛ₰, 5 ℛ₰, 10 ℛ₰, and 50 ℛ₰) and 1945 (1 ℛ₰ and 10 ℛ₰ only). After the war, the Allies issued
