Types
Two versions of the dollar were minted in 1971. The coin that the U.S. Mint issued for general circulation was 75 percent copper and 25 percent nickel. The U.S Mint struck about 110 million copes of this coin in Philadelphia and Denver. The San Francisco Mint produced a silver version of the coin issued only in proof sets. About 7 million copies of this coin made of 80 percent silver and 20 percent copper were issued.
Values
The copper-nickel version of the coin only fetches a premium if in high grades. A 1971 dollar graded as uncirculated, with practically no wear and only slight imperfections, can sell for $4 to $6 in 2010 prices. The silver proof sells for $8 to $10 in 2010 prices.
Fun Fact
The official Apollo 11 insignia was the direct inspiration of the design on the reverse of the 1971 dollar.
