They cut one open for me at the yard and Jghilino is correct. There is some copper (not a lot), but it was caked in a tar-like mess. I think it's worth it for you to take one apart and decide for yourself, but for me, a lot of work for very little reward on the one I did. They kind of remind me of 3-4 small transformers off low grade boards in a row covered in tar.
