This was a civil decoration for 50 years of true and faithful service to the state. The obverse of the decoration features the ruler of Anhalt’s crowned cypher. The reverse has “Fur funfzigjahrige Diensttreue” (For Fifty Years True Service). Obviously, since this was for fifty years of service, it was not a common decoration. It has a beautiful patina and comes with a wide green and white ribbon. This decoration was given from the period of 1864 to 1918. Judging from the look of the decoration and ribbon, I would say this particular example was issued in the 19th Century.
