The 1943 Nazi 5 Reichspfennig coin, an emergency wartime issue, is a zinc coin featuring the German eagle (Reichsadler) with a swastika on the front and "5 Reichspfennig" with oak leaves on the back, with the 'A' mint mark signifying it was struck in Berlin. These common coins were produced from 1940-1944 and reflect Germany's shift to cheaper materials during World War II, making them interesting historical artifacts.
