Original 1923 Weimar two million mark banknote. In circulated condition, a little rough around the edges. It is one sided. I am not saying you need to have a reminder why inflation is bad, but here it is. At the peak of hyperinflation in November 1923, 1 US dollar traded for 4.21 trillion marks (yes, trillion: 4,210,500,000,000 marks for $1). A loaf of bread that cost 160 marks at the end of 1922 cost 200 billion marks by late 1923.
