:rolleyes: Hello Micha !! WWaaaaoouuuhh !! "the Frankfurt telephone book" ?? I've to work a little !! Good luck for your hunt, man, but I've seen a part of your collection on the web (different site) and I think you're a real specialist !! If you take a pic of each one of yours.... What a beautiful book !! Not ? Well, I've found a website called "Encyclopedia of silver marks", very interesting, there is German silver marks before and after 1886 !! You can find it at : http://www.925-1000.com/ Perhaps we can identify some iron cross's makers..... ?? All the best Junger1418 :catjava:
