How much is a Hundert Milliarden Mark dated 30 October 1923?

A Hundert Milliarden Mark (100 billion marks) dated 30 October 1923 is a notable example of hyperinflation in Weimar Germany. During this period, the value of the German mark plummeted, making such high denominations practically worthless. While it may have had a face value of 100 billion marks, its actual worth in terms of purchasing power was negligible. Today, it is primarily of interest to collectors and historians rather than having any significant monetary value.
