50 000 000 000 Mark

Lörrach's municipal notgeld at fifty billion marks dates to the absolute peak of the Weimar hyperinflation, when local authorities across Germany were legally compelled to print their own emergency currency simply to pay wages. The Wiesentäler Handelsdruckerei Carl M. Auer was a regional commercial press — not a specialist banknote printer — and it shows in the production quality typical of these municipal issues.

By November 1923, the Rentenmark reform rendered the entire series worthless overnight. Most were discarded; survivors exist largely because collectors were already active during the inflation itself.
