1923 Germany Notgeld Rhine-Ruhr 50, 100, and 500 Million Mark
Things were very grim in Germany. War, human atrocities, ruthless dictators, crushing defeats, and financial collapse plagued the nation. German cities issued their own coinage since the imperial coins were completely worthless. It was an emergency and replacement money was needed. That's what notgeld means: emergency money.
This piece of notgeld from the Rhine-Ruhr region is particularly gruesome. The coin was struck at 33 mm in diameter, designed by the famous German medalist Karl Goetz. Greek god Prometheus appears on the obverse, chained to a rock with an eagle eating his liver as part of his eternal punishment by Zeus. On the reverse a child appears in an eternal flame. There are incused letter on edge: NOTGELD.
There are three denominations of the Rhine-Ruhr notgeld:
50 million mark -- brass
100 million mark -- white metal or silvered bronze
500 million mark -- gilded metal
I own a full set of 3, plus an additional 2 - 500 million mark coins for a whopping 1.65 billion marks. To put it in relatable context: by late November 1923, one US Dollar was equal to 4.21 trillion marks.
