I know someone else on here asked about sim cards and I gave him the answer I found. There are about 1000 sim cards in an ounce of gold so all you would have to do is a little math to see how much $ worth you do have. Also, I cant recall if he found a buyer per pound but if you look for the thread than he may have but I can't recall or not or you can look and send him a pm and ask him.
