Tanacat Thank You for taking my suggestion into consideration. When I said Auction House, I meant one on those smaller ones like that one on TV called galley 63 . It's a smaller one than the ones in New York and other big cities. A lot of towns have them and use local experts to appraise items like yours. You might have to act like your interested in selling or they might not want to waste their time obviously. Also, I found this button some years ago and called my town Historical Society and they were very helpful, that's why I suggested that idea. They told me it was a post- Commemorative Battle of Waterloo Button an that these type of buttons were popular in those days. I believe the front is silver. They couldn't give me a value because museums don't talk in terms of monetary value, just historical value but the guy I spoke with was very interested and said it was quite rare. I was out detecting with Dan (del) and he said he found one also but just not in the same condition, guess he found the other rare one. So, maybe you have a chance of finding the other one if it exists and the other piece of silver bar which I personally believe is still out there. It looks chopped by a plow, so it must still be out there .
