The 1984-D Kennedy Half Dollar is a tougher date in the Clad Kennedy Half Dollar series. It is hard to come by even in MS65 condition. In MS66 it becomes more difficult and is considered a scarce coin in this grade. In MS67 condition it is very difficult to find.
There are very few coins available in this grade or higher, making it one of the key dates in the Clad Kennedy Half Dollars series in Gem condition.
