75 Pfennig

Ellerbek is a small town immediately adjacent to Kiel in Schleswig-Holstein, and like hundreds of German municipalities in 1921, it resorted to printing its own Notgeld when the Reichsbank failed to supply adequate small-denomination coinage during the postwar inflation spiral. The 75 Pfennig denomination is moderately unusual — most municipal issues clustered at 25, 50, and 100 Pfennig — suggesting either a specific local pricing need or a deliberate effort to issue a complete set across an odd denomination spread.

Ellerbek's series is not among the extensively documented collector-targeted Notgeld issues, which implies it was printed for genuine transactional use rather than to exploit the philatelic market that had already emerged by 1921.
