I would like to find out the name and other info about the refinery whose hallmark is on this 10.17 troy oz bar. I spent hours looking through the silver mark encyclopedia but I couldn't find a match. Any help would be appreciated. I'm sorry I don't have an web image to link this post to but the bar...
That is the mark for Universario. I had to identify it myself today and found a 1 oz coin at our local silver shop with the symbol and name for the refinery. Hope this solves a mystery. .
