Would not call that a counterfeit, as there was no such coin. :) Prussia issued that piece as a silver coin (diameter 38 mm) in 1913 and 1914. If the piece in your pendant has that size, it will be a third party gilded coin. If it's smaller (the 5M gold coins, issued until 1878, had a diameter of 17 mm), it would be a fantasy piece combining the specifications of the older gold coin and the design of that newer Wilhelm II coin ...
