Found this little one piece button on a site dating from all through the 1800's. The soldered on shank is missing and it is very worn. I can still make out some details and I have made a noble attempt to draw them for you. What I get out of it is a flag, with POSSIBLY a small "V" under it (could just be a part of something else but it is one of the stronger details) with some other things around it. The backmark is in depressed letters with two concentric rings close to the shank. I can't make them out but they look like they're in the old english style. Anyone out there brave enough to guess on this one?
