Nazi coins were produced by the Nazi government in Germany during the time of Adolf Hitler's reign. These coins typically featured the Nazi symbol, a swastika, and often had inscriptions that praised the Nazi regime or glorified Hitler's leadership.

Communist coins were produced by communist governments in various countries, such as the Soviet Union and China. These coins often featured communist symbols, such as the hammer and sickle, and inscriptions that praised communism and the communist regime.

Both Nazi and communist coins were made using 3D printing technology, allowing for intricate and detailed designs to be produced. These coins were made to serve as propaganda tools, spreading the ideologies and values of the respective regimes. However, they are now often collected as historical relics or as symbols of the atrocities committed during these regimes.
