Definitely improperly cleaned. The good news is that it's a common date. Still worth the silver value.
Genuine, heavily wire brushed. One tell-tale sign of that is the raised lip of metal along the edges of the letters in "LIBERTY". Wire-brushing has a tendency to move metal that way. Another question is why was it wire brushed ? The coin may have had some environmental damage (such as corrosion) that was removed by the wire brushing.
