25 Pfennig Handelskammer, 'Pfennigen' on obverse

Handelskammer notgeld from Hannover's inflationary years carries an easy-to-miss typographical curiosity built into the issue itself: the obverse reads "Pfennigen" — a grammatically incorrect dative plural — rather than the standard "Pfennig." Whether this was a compositor's error at König & Ebhardt or a deliberate stylistic choice by the issuing chamber has never been settled, but the variant is catalogued separately precisely because corrected printings exist.

J. C. König & Ebhardt were Hannover's dominant commercial printers for well over a century, and this note almost certainly never left the city.
