50 000 000 000 Mark

Buer — now absorbed into Gelsenkirchen — was one of hundreds of German municipalities forced to print its own emergency currency during the hyperinflation spiral of late 1923, when the Reichsbank simply could not supply notes fast enough to keep pace with collapsing purchasing power. By the time denominations like this fifty-billion mark note were being issued locally, the figure itself was almost beside the point; wages were being paid daily, sometimes twice daily, and notes were spent within hours of receipt.

Local Notgeld at this scale was typically printed on whatever stock was available, often single-colour, with minimal security features. The Stadtkasse Buer issues from this period are not scarce as a type, but individual examples in sound condition are harder to find than the raw survival numbers suggest — heavy handling in active daily circulation took a toll that hoarded Notgeld never suffered.
