Thankyou. Just spent two hours trying to post this picture. Still learning how to downsize photos. Thanks for looking. I'll try to post the back. I've really enjoyed looking at everyones posts.
I did some googling and I think they call it a solid cast button. But I'm no expert. I was gratefull to find it. There doing some logging near where I live and they leveled what I think was an old homesite from the mid 1800's.
