I have identified this piece as best I could. I know it's German by the symbols that are (appear to be) a moon and crown. My piece has 2 moons and a crown - not sure if this means anything. Does it?
What could the right-most marking be?. I originally though it to be a 01, but now I think it is an 'M'. I could not find anything similar in the German Silver section.
Also, I don't exactly know what this item is. Could you please identify it for me. The diameter is approx. an inch.
Your help is appreciated. Thank you.
