As I was cleaning out my old filing cabinet (OK, OK my wife was cleaning it out!!) she found a bunch of Series EE Savings Bonds that my grandmother bought for our daughter 5 years ago. I don't have a clue how these things work. When do they mature? Can they be cashed prior to this? At what price? And finally, what is their value? I mean they say $50 right on them, but how do I know what interest they are earning?

Thanks!!!
