Big Silver Score

I was visiting my brother in Virginia for a few days and we had a few hours before I had to leave for the airport so we decided to check all the banks for half dollars and big dollar coins. The second bank we went to I asked if they had half dollars the Teller said I have $1 and asked the teller next to her if she had any halves the other teller had $47.50 in halves I bought them all and as the Teller gave them to me I saw 3 rolls that were beet up and looked really old. Part of the paper on the roll was missing and I saw silver edges I ran out to the car and opened them and every single half dollar was silver 3 solid rolls most of them were 1964's in excellent condition one of the rolls even had 2 extra halves. In total I got 49 half dollars from 1964 and 13 40% By the way none of the other 15 banks had silver. But now my brother wants to start CRH.
