patina

Found this item in the woods of Luxembourg. The site has produced a couple of Roman coins but mostly 1700s/1800s/1900s stuff. Appears to be brass as it has a nice green patina. My first thought was a Roman brooch but I have realized that is probably wishful thinking. Any info is appreciated...

Hello everyone, I'm new to the forum, but if yesterday was any indication, I think I might just get hooked on treasure hunting... My brother and I were goofing around on his property with my metal detector near where he found a Catawba Indian arrowhead last spring. Anyway, the thing started...
