An original bronze German Kriegsverdienstmedaille (War Merit Medal). This award was instituted on 19 August 1940, to reward those civilians who were helping in the German war effort, predominantly those working in war factories. A wiki entry estimates approximately 4.9 million had been issued by the end of the war.
Something Young Indy might have had in his pocket... a Belgian 10 Centime coin:
And something he wouldn't... German occupation Belgian zinc coins from 1941-1944:
Reichspfennigs from 1925 and (pre-Swastika) 1936:
In the aftermath of war, the Bank Deutscher Länder was founded 1 March 1948 to manage currency policy in the American and British occupation zones. On 1 November 1948, state central banks in the French zone, which had adopted Deutsche Mark in June, joined the BdL. In May 1949 the Federal Republic of Germany (West Germany) was founded, however, the BdL remained subject to the control of the US, the UK and France until 1951.
These particular coins were only issued under the BdL in 1949 - from 1950 they bore the inscription 'Bundesrepublik Deutschland'. These examples were minted at Karlsruhe ('G') and Hamburg ('J').
My one and only Italian coin from the fascist era: a 1942 10 Centesimi piece, with the 'XX' representing the 20th year of Mussolini's rile.
