Grasshopper - You've probably already figured this out but that's a hell of a nice point. The folks on the board will be able to tell a lot about it, but first could you please tell where you'd best guess the point is from?
I honestly cannot really say. My grandfather gave it to me inside a mini portrait/old pin holder thingy of an ancestor. My whole family is from NY so my best guess would be that, but there's definitely a good chance it was from somewhere else. I'll ask around and see if I can get some more info.
