I have this spoon made of a french coin dated 1782, value 400 something ;) I can't describe the mark but I think it is pretty visible in the photo. I better let you with some of them. I will appreciate your comments. Thank you.
I will have to leave the identification of the marks to other members who are more knowledgable than myself. You can help them out by cleaning the marks only then reshooting them straight on. Use a well chewed wooden toothpick with a small amount of silver polish, that should work well.
