1 000 000 000 Mark Darlehenskassenverein

Triftern is a small market town in Lower Bavaria, and by late 1923 even rural cooperative lending societies — Darlehenskassenvereine — were printing their own emergency currency to keep local commerce functioning. The Reichsbank's printing infrastructure had completely lost the race against hyperinflation by that point; a billion marks was not an exceptional denomination but a routine one.

Local Notgeld of this type was produced in very short runs, often on whatever paper stock was available, and had an extremely brief circulation window before the denomination became worthless again within days. The Rentenmark reform of November 1923 rendered the entire series void almost immediately after issue.
