Based on the provided information, numerous United States coins contain silver, particularly those minted for general circulation in or before 1964. These coins, often referred to as "junk silver," are valued for their silver content rather than any specific numismatic rarity.
The most common U.S. coins that contain silver are specific denominations from this earlier era. This includes silver dollars, half dollars, quarters, and dimes. Any of these coins with a date of 1964 or older were produced with a composition of 90% silver. In addition to these historical circulation coins, modern silver bullion coins are also produced, which are intended for investment purposes and are valued for their high silver purity.
