Brucie, are you talking about the ends with the small gold "fingers"?
I sent an envelope of them off a while back. Let you know how that ends up.
I have a whole box full of the silver mylar ribbons.

When you get enough of them you could have someone refine them for you to see what comes out of them. There is some good refiners over on the "other" forum but it takes time to get to know them.
