Weimar continued to print money around the clock, creating hour-to-hour hyperinflation. Fabulous stories abounded of money being carted around in wheelbarrows and being used to stoke furnaces. One famous story centered on a Freiburg University student who ordered a cup of coffee listed on the menu for 5,000 marks; by the time he ordered a refill, the second cup cost 9,000 marks. Another told of an insurance policy redeemed to buy a single loaf of bread. The American dollar, which had traded for 1,500 marks in 1922, was worth 4.2 trillion marks by the end of 1923.
