You'll have to weigh it and get it tested for silver. If it was altered, what was it altered from? A 79 CC in VG is over $200. I am leaning fake.
My bad, I was thinking of the 1878 CC mintmark style. Shows you how often I deal with the doldrum that is Morgan Dollars
To me its a very environmentally damaged 'coin' BUT there is no overseeing any damage that could cause the trigger look on the "9" - I am going with it weighs wrong, rings wrong, and is magnetic.
