Gold Medal with Yellow Ribbon

Centenary Medal (Prussia), also known as the 1897 Wilhelm I Commemorative Medal. These medals are the same type, established on March 22, 1897, by Wilhelm II to commemorate the 100th birthday of his grandfather, Emperor Wilhelm I.  Key features of the medals include: Material: Typically made of bronze, sometimes with a gilt surface, and in rare cases, gilt silver or zinc. The bronze used was often sourced from captured French bronze during the Franco-Prussian War.  Obverse: Features a right-facing effigy of Wilhelm I in military uniform, wearing a mantle and Pickelhaube (spiked helmet). The inscription reads "WILHELM GROSSER DEUTSCHER KAISER KÖNIG VON PREUSSEN".  Reverse: Not visible in the provided image, but it generally features the crowned cypher of Wilhelm I, surrounded by an inscription and oak leaves.  Ribbon: Yellow, and in the image, it is visible as the fabric from which the medals are suspended.  Sizes: The most common size is 41 mm in diameter, but other sizes like Prinzengroße (29-30 mm) and miniatures (15-16 mm) also exist.
