In two weeks, we leave to visit my ancestral villages in the C.R. Then on to Germany to visit family. When I was in Europe (Germany amd France) in l965, porters and cab drivers were very interested in receiving a " Kennedy Half" dollar as a tip. Are there any current U.S. coins that might be particularly desireable? The Susan B Anthony dollar was not popular here, what about over there? Also, would there be special interest in our state quarters? Thanks for any answers.
