I have aquired a luncheon knife that I believe to be silver but I cannot find this mark anywere. Can someone clue me in? It is a single circle with AP below a dog, lion, or boar, take your pick. There are no other markings or initials on the piece.
No Idea at all, but post a picture and we’ll take a look. Just to help narrow the search down a bit, tell us what country you acquired it from.
