I love it - in fact being a collector of such things I am very jellyarse - a wonderful find. Probably brought back by a WWI Serviceman as a souvenir. To me that medal is the best find I have seen on here yet.
.900 Silver and weight 7.50 grams and diameter 25mm
Should have a triangular black and white ribbon.
German warrior merit silver medal Prussia, 1872 version. The Warrior Merit Medal German: Krieger-Verdienst was a military decoration of Prussia. Established by Friedrich Wilhelm III, it was primarily awarded to troops not in Prussian service. The first recipients were members of the Imperial Guard grenadier company guarding the Russian imperial residence during Friedrich Whilhelm's visit to St. Petersburg in 1835. The later version of the medal depicts the crowned cipher of King Wilhelm I on the obverse. The reverse is also inscribed KRIEGER VERDIENST and surrounded by a thicker laurel wreath than the early version. The medal is suspended by a ring suspension and hangs from the black with white stripes combatants ribbon.
