10 000 000 000 Mark

Frankenstein in Schlesien — now Ząbkowice Śląskie in Poland — was one of hundreds of German municipalities forced to issue emergency currency during the hyperinflation of 1923, when the Reichsmark was collapsing so rapidly that the Reichsbank simply could not print denominations fast enough to keep pace with daily price changes. By October 1923, ten billion marks would not have bought a loaf of bread. Municipal notgeld at this level of denomination was often printed on whatever stock was available locally, which accounts for the variation in paper quality across surviving examples from the same series.

The Rentenmark reform of November 1923 rendered all such issues worthless essentially overnight.
