[QUOTE="John Burgess, post: 7561727, member: 105098"]Half dollars made from 1965 through 1970 are made of two outer layers containing 80% silver and 20% copper with an inner core of 20.9% silver and 79.1% copper (net composition: 40% silver and 60% copper). As far as the silver,when separated from the copper, 0.1479 troy oz of .999 fine silver. I think all of this was said in different posts, but that sums it all up.[/QUOTE]
