The proof penny has separation lines on the obverse lettering as well as the ear on the Kennedy half dollar, making them both DOUBLED DIE OBVERSES(DDO).

This 1983 P D Mint Set and 1983 S Proof Set are a must-have for any coin collector. The sets include half dollars with rotated dies and are composed of copper with a fineness of 0.917. The coins were minted in Philadelphia, Denver, and San Francisco and have been lightly circulated and not circulated at all.

The sets are perfect for those interested in business and proof strike types and are a great addition to any collection. The coins are ungraded and come with a KM Number of 0. This United States coin set is a rare find and should not be missed out on.

In 1982 and 1983 there were no government issue Uncirculated mint sets, making it quite difficult to come across good examples of these coins when they are needed, and very expensive when bought individually.
