This 1970 US Mint set includes 10 coins of different denominations, ranging from .50 to .01. The coins are uncirculated and come in their original government packaging (OGP). The set includes coins made of silver and copper, with a fineness of .40 for the Kennedy half dollar. These coins were struck in a business strike type at the PDS mint locations, but they are ungraded and uncertified. The set is a great addition to any coin collection and a piece of United States history.
