1923

Weimar

The paper mark stops working. The Rentenmark is the stop that follows.

Crowded Berlin bank interior during the German hyperinflation period, customers packed at teller windows.
“In a Berlin Bank” — customers during the German inflation crisis (Library of Congress).Public domain — Library of Congress (LCCN 2014716642); no known restrictions.

In 1923 the German mark lost practical use as a unit. The sequence starts with war finance and the Ruhr, not with a slogan about printers.

The Rentenmark is how that particular collapse was stopped. It is not a model for a later trade, and it is not John Law’s 1720.
