Very cool story. My daughter is 15 and spends every dollar she gets her hands on as soon as possible. I've been buying her silver Eagle coins to try to teach her the value of money, but every once in a while she asks me how much they're worth because she wants to sell them to buy junk. I don't allow that of course, but she is a work in progress and not ready for a contest like this. Kudos to your buddy for teaching his family valuable lessons that will be fun to learn.
