U.S. 1959 and 1960 5-Coin Silver Proof Sets.
Much more affordable than earlier U.S. proof sets and now well over 50 years old, these are the least costly of their vintage. They were some of the last regular proof sets to include a 90% silver dime, quarter and half dollar in addition to the cent and nickel. Many sets were later broken up to obtain coveted individual Franklin silver half dollar proofs, which were issued only in these sets. Sealed U.S. Mint cellophane packaging protects the beauty of these finest-quality proofs.
