Yeah, I saved up a bunch of it and took it to the yard to see what would happen. When I told the guy it was tinned copper he took one, hit it with a file and gave me #2 copper for it. So now I know I can mix it in with my other #2. I'll just hit one or two of them with my file so the guy can see what it is. I say that because there's always a different guy at the scale when I go and the next guy might not know what I have.
