Belt buckle!

Today was a really bad MD day. I spent about 2 hours searching through the most trashy area I've seen, and didn't find anything else than rubbish. On the way back however I felt the urge to quickly go over an area longer up the forest. After a while I got a really strong signal, which turned out to be a belt buckle. Now, I have no idea what kind of metal it is. At first I thought silver, but after further inspection, I found out that it can't be.. It seems too rough and dark. I don't know how old it is either.



Anyway, I'm done with the worst part of the forest now, and tomorrow I'm going up instead of down. This part has been used way more the last 40-50 years, so I hope I'll find some coins there.
