Those Kennedy Half Dollars look great. Several years ago, when silver was upwards of $40 - $50 an ounce, my local coin shop was busting open mint rolls of 1964 Kennedy Half Dollars. It was almost sacriligious to me. They said that the price of silver was so high that the 'melt value' was higher that the numismatic value. I was mortified. I got a few at an astronomical price, then returned for the loose Kennedy Halves when the price came down.
