Prinzen Iron Crosses

Non-Magnetic: EK2 and EK1 screw (which makes these neusilber).
Magnetic: EK1 pin (which make this one real silver - but I could not see a silver content mark).

Interesting results. However your conclusions are not quite accurate. A magnetic reaction indicates a steel core, not a silver frame. A non-magnetic reaction indicates a core made of non-ferrous material. With Deumer this is usually brass. Again, the frame of a Deumer may be silver or neusilber, but both materials are non-magnetic. In my opinion all your Deumer EKs have neusilber frames.

Thanks for all your opinions and clarification.

The screw EK1 with patriotic box came from Emedals...
