About this Product Full Product Name
The 1970 Proof Set is a signifigant set because it contains a Proof Kennedy Half Dollar and the Kennedy Half Dollars, which in general were not issued for circulation in 1970. The set in total includes the following 5 coins:
  • Lincoln Cent
  • Jefferson Nickel
  • Roosevelt Dime
  • Washington Quarter
  • Kennedy Half Dollar
The proof coins in this set were struck at the San Francisco Mint.

The term "Proof" refers to a method of manufacture and NOT the condition of a coin. Proof coins can usually be distinguished by their sharpness of detail, high wire edge, and extremely brilliant - mirror like surface.

Proof coins are made from highly polished dies. The coinage blanks are also polished and cleaned. They are hand fed into a coinage press one at a time, with each blank receiving 2 or more strikes from the dies to bring up sharp - high relief details. It is done at slow speeds with extra pressure. Finished Proofs are individually inspected and handled by gloves or tongs prior to being placed in sonically sealed plastic cases.

All Proofs are originally sold by the United States Mint at a premium.
