Silver Eisenhower Dollars
September 10th, 2009
Although the Eisenhower Dollars produced for circulation did not contain any silver, the US Mint produced collectible versions of the coins which contained 40% silver. Struck at the San Francisco Mint, these modern silver dollars have an outer layer of 80% silver and 20% copper bonded to a core of 20.9% silver and 79.1% copper. The coins were produced in both uncirculated and proof versions and sold individually from 1971 to 1974. The uncirculated coins came in blue envelopes and came to be known as “Blue Ikes”. The proof cons in brown boxes came to be known as “Brown Ikes”. Silver versions of the Bicentennial 1976 Eisenhower Dollar were also produced. These were sold in 3 coin sets, along with the half dollar and quarter.
