Got this today, it's supposed to be silver. I tested it in a few spots and it seems to be but I can't identify the single mark I see. I'm sorry for the photo of the mark, it's the best I could do using a lit magnifier and my iphone. If anyone can tell me if they recognize this mark I'd appreciate it. Hopefully it's what I was told it is (antique, European silver,etc) Above the mark it looks like a K4?
Thanks for taking the time to look.
