1 000 000 Mark Biebrich am Rhein

Biebrich am Rhein was absorbed into Wiesbaden in 1926, making this million-mark note one of the last independent municipal issues from a city that would cease to exist as an administrative entity within three years of printing it. The Stadtkasse — the city treasury, not a bank — issued emergency currency because the Reichsbank simply could not supply denominations fast enough during the hyperinflation peak of 1923, when prices were doubling in hours rather than days.

Local printing kept costs down but quality variable. Municipal Notgeld at this denomination was often issued and redeemed within weeks, which is why intact survivors are more common than their brief circulation window might suggest — many were pocketed as curiosities before they could lose all purchasing value.
