Poland – Warsaw Ghetto – 20 Zlotych – 2008 – Proof Silver Crown – The Warsaw Ghetto was the largest of the Jewish ghettos located in the territory of German General Government during the World War II. The Warsaw Ghetto was established on October 16, 1940. At that time, the population of the Ghetto was estimated to be 440,000 people, about thirty-eight of the population of Warsaw. The Nazis then closed the Warsaw Ghetto from the outside world on November 16, 1940, building a wall with armed guards. It is estimated that during the next few years over 100,000 people within the Warsaw Ghetto died as a result of disease, starvation or murder by the Germans. Another 250,000 to 300,000 were sent to their deaths at extermination camps, mainly Treblinka. Less we forget, this beautiful proof silver crown is a reminder to all of the horrors of that time.
