"By July 1922, the German Mark fell to 300 marks for $1; in November it was at 9,000 to $1; by January 1923 it was at 49,000 to $1; by July 1923, it was at 1,100,000 to $1. It reached 2! 5 trillion marks to $1 in mid-November 1923, varying from city to city. So the printing presses ran, and once they began to run, they were hard to stop."
"When the 1,000-billion Mark note came out, few bothered to collect the change when they spent it. By November 1923, with one dollar equal to one trillion Marks, the breakdown was complete. The currency had lost meaning."
