Eisenhower dollar proofs were the first silver dollar proofs issued to the general public by the U.S. Mint (the few made earlier are rare and extremely costly). It revived the traditional-size silver dollar which had been suspended after the final 1935 Peace silver dollar. In 1972 just 1.8 were issued in this 40% silver proof quality. Overall, only 6% of Eisenhower dollars were struck in silver and less than half of those in this finest-quality proof form, with deep-struck engravings and dazzling mirror surfaces.
