As a follow up to my last post, I will try to explain in a little more detail. When the fake pieces of the three discs mentioned above appeared in 1994, there were known originals of two of them for minute comparasion. The fake discs for the ultra-rare Prussian State Kripo disc were counterfeited in at least three different metals...bronze, nickel-silver and silver plated, but all were struck on the SAME counterfeit dies. The Fake Gestapo disc was produced in the correct nickel-silver (neusilber)., and the Geheime Feldpolizei (GFP) disc was produced in neusliber. All were die struck in very high quality. The fake "Gestapo" disc was the first to be unmasked. Then shortly afterwards the Prussian State Kripo disc was equally discredited. That left ONLY the GFP disc that could not be effectively declared a fake....because the only known original example of that disc had been used to produce the counterfeit. A rather poor illustration of it is shown in a 1989 published Osprey book "German Military Police Units 1939-45" written by Gordon Williamson, and illustrated by Ron Volstad. Today, the whereabouts of that original disc is unknow to the collecting world, but probably still in the possession of the persons who were involved in producing the fake discs. Since there is no other known original example of the GFP disc, by which to use to unmask the fake pieces....no one that I know can "tell you for sure", but in a case like this, a little bit of common sense can go a long way toward saving one's money.
