5 Pfennig - Crefeld

Krefeld issued this iron notgeld piece in 1918 as the German war economy had stripped conventional coinage metals entirely from municipal circulation. The Rhineland textile hub was among dozens of industrial cities forced to produce their own emergency small change that year, but Krefeld's iron pieces are notable for the specificity of their Funck cataloging — the 84.4A designation distinguishes a die variant within a tightly sequenced local issue, not merely a compositional footnote.
