50 000 Mark

Kaiserslautern was one of hundreds of German municipalities that issued emergency currency — Notgeld — during the hyperinflation of 1923, when the Reichsmark's collapse outpaced the Reichsbank's ability to supply denominations large enough for daily transactions. By mid-1923, 50,000 Mark barely covered a loaf of bread, and municipal authorities were effectively functioning as emergency monetary authorities by necessity, not by design.

Local Notgeld of this period was typically produced by regional printers on short notice, with quality and paper stock varying considerably between issues. The Stadt Kaiserslautern series has no documented printing error variants of significance, and most surviving examples come from uncirculated remainders — the denomination was overtaken by inflation so quickly that much of it never left the issuing office.
