Reminds me of a story of one of my finds. I found it in a lake and it was caked with sand. I just put it in my junk box. I had a party with a few of my metal detecting friends and we were talking about junk. I pulled out my junk box so they could see some of the things I find.
One of my friends (Unfortunately the one that drowned detecting) Tom Weaver saw this thing and said he saw two swords on it. I knew it was a pin because there was a pin in back but that was all that was visible. I just thought it was a kids toy. We boiled hydrogen peroxide and kept putting it in it. Well this is what it was. How it ended up in a lake in the middle of Michigan we will never know.
For those that do not know what it is. It's a WW2 German wound badge
