Right, F is Stuttgart (see the previous post). A well preserved piece should cost between €2.50 (vz/EF) and €5 (st/unc). Also, it is still worth its face value, ie. you would get 51 cent for it at a Bundesbank branch office. The best thing to do IMO is, keep it as a souvenir since it reminds you of your friend ...
