I have a couple of silver coins in my small collection and was wondering if anyone had a ballpark idea of about what they are worth. One is a 1922 silver dollar. I believe these were referred to as "peace" dollars since they were made right after WWI. I don't know how coins are graded but it is in very good condition. It does not appear to have a mint mark on it. The second coin in a JFK half dollar from 1964. I believe this was the first year they were made and if I remember the silver content is pretty high. Are these worth more as coins or for their silver content? Thanks in advance!
