This is a set of twenty 1964 Kennedy silver half dollars in gem proof condition. They were produced by the US Mint in Philadelphia and have a fineness of 0.900.
The set of twenty coins also includes a free 1964 quarter in proof condition. What I love about these 1964 quarters and half-dollars is that in 1964 and I was there, -those were the days. And that;s still true today. PUT some silver away today. WE are the low price leader.
