Hi guys!
What can I say about these?

Ref.- Mark reads "Z & CO 20".
Anything more you can show or tell? Object description. General area of world where object was located. Numbers on silverplate (site Library) often indicate a European source but perhaps not in this case.

If the case were for 20 grams silver in the plate, this would seem to be bottom grade. See here : https://www.925-1000.com/a_platenumbers.html

But that's not a conclusion, yet!

3 forks. One of them from Italy (cosa silber 90) and two probably from Germany.

Hello, the Z&Co is most likely Ziech and Co. from Duesseldorf, Germany. Cosa is a mark used by Sandig and Co. from Liegnitz, Silesia (today Legnica, Poland). Better pics of front, back and mark (one pattern for each thread) might help in the future. Regards, Bahner
