What Hallmark is this please help ?

Recommended Posts

Hi, Constantin.

Your hallmark is probably a german one, before 1886, the eagle face left (with multiple variations) is very similar with the one for the City Mark Aachen, North Rhine-Westphalia. 

GSM letters inside cartouche are most probably the initials of the maker. There are plenty of makers, so we can only guess. SM can be initials from Silberwaren or Metallwarenfabrik, I can not find this specific GSM group of letters mark, the sources are limited unfortunately.

800 is obviously the purity of silver alloy, very common for Prussia and Germany cities.

I am sorry I can not help you more. Maybe @sixgun or @daca have another opinion?🤗

Kindest regards,
