I would like to identify a hallmark on an argentinian silver&gold dagger in order to find the date the work was made. I've searched in several databases and I cannot find it. I don't know that much, but I've read that Decimal Standards Marks can help to find out the place and date of one piece. This one has a 900 one on it. I would appreciate if you can help me. This is my first time in this forum, so I apologize if this is not the right place to ask. Thank you very much.
