They don't have anything to do with die or lot numbers, apparently, but instead, they are a number referencing the Czech Proof House for Arms and Ammunition according to Act No. 156/2000 Coll., On verification of firearms, ammunition and pyrotechnic articles. They replace the previous CZ mark on the tin.
