Just 1.3 million were issued in this 40% silver proof quality, the second-lowest proof mintage in the Ike dollar series. 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. The Eagle on Moon reverse honoring America's space program began under Ike's administration.
