1 Pfennig - Mühlheim am Main Offenbacher Schrauben Industrie

Issued by the Offenbacher Schrauben Industrie — a screw and fastener manufacturer in Mühlheim am Main — this is a piece of German industrial notgeld, the kind of emergency token that proliferated during the severe small-change shortages of the early 1920s. Factories and businesses across Germany issued their own pfennig denominations when the official supply collapsed under inflationary pressure, and zinc was the practical choice: cheap, available, and easy to stamp.

Hasselmann catalogued hundreds of these manufacturer-specific issues, most surviving in small quantities and rarely found in circulation wear.
