State Criminal Police (Staatliche Kriminalpolizei) KRIPO ID Disc. These quality discs (State Criminal Police) were always struck in bronze. These discs came out in 1937 on order of Himmler and were carried by state criminal police (Kripo) while on duty having the number of the officer stamped onto the back of the disc. The same number would be found on the ID card of the officer. All German police warrant discs were normally carried on a chain, which was not covered by the regulations. It was the officers choice. This example comes with a 1994 dated Don Bible Certificate of Authenticity. Don Bible wrote the book on these.
