This is an authentic 1918 German 10 Pfennig official necessity coin (Notgeld) issued by the city of Crailsheim in the Federal state of Württemberg. The obverse features the city name CRAILSHEIM positioned above a detailed panoramic view of the city, with two coats of arms displayed at the bottom. The reverse displays the denomination number 10 centered within a pearl circle, surrounded by the German lettering KLEINGELD ERSATZ and the commemorative year 1918. Local authorities commissioned this emergency coinage to mitigate the severe national shortage of circulating small change during this historical period. Minted in iron by the Stuttgarter Metallwarenfabrik Wilhelm Mayer & Franz Wilhelm e.K., this distinct octagonal token features a plain edge, a precise diameter of 20.7 mm, a thickness of 1.2 mm, and weighs 2.7 grams.
