Several United States coins are made of silver, with the silver content varying by the coin's denomination and year of mintage. For common circulating currency, a key date to note is 1964. Dimes, quarters, and half dollars minted for circulation in 1964 and earlier are composed of 90% silver.
After 1964, the composition of these coins changed. Half dollars minted between 1965 and 1970 contain a reduced silver content of 40%. Additionally, historic silver dollars, such as the and Peace dollars, were also made with 90% silver. These older coins are often referred to as "junk silver," a term indicating their value is primarily derived from their silver content rather than numismatic rarity.
The U.S. Mint also produces modern bullion coins for investors and collectors. The American Silver Eagle, first minted in 1986, is a prominent example, containing one troy ounce of .999 fine silver. Beyond these, certain commemorative coins and special proof sets issued by the U.S. Mint also contain silver.
