Only 5% of all Eisenhower dollars were struck in 40% silver, exclusively by the San Francisco Mint. And this 1974 issue was the last to carry the Eagle on Moon reverse since the final issues in the series featured a special Bicentennial reverse. The magnificent bust portrait of President Eisenhower followed the passing of this great American in 1969. No traditional-size 38mm dollar coins and no dollars with any silver content have been issued for commerce since. Brilliant Uncirculated quality.
