SILVER LIBERTY DOLLAR DATED 1990 1 OZ FINE SILVER The American Silver Eagle is the official silver bullion coin of the United States. It was first released by the United States Mint on November 24, 1986. It is struck only in the one-troy ounce size which has a nominal face value of one dollar and is guaranteed to contain one troy ounce of 99.9% pure silver. It is authorized by Title II of Public Law 99-61 (Liberty Coin Act, approved July 9, 1985) and codified as 31 U.S.C. § 5112(e)-(h). Its content, weight, and purity are certified by the United States Mint. In addition to the bullion version, the United States Mint has produced a proof version and an uncirculated version for coin collectors. The Silver Eagle has been produced at three mints: the Philadelphia Mint, the San Francisco Mint, and the West Point Mint. Starting in 1986, the US mint began producing the Silver Eagle dollar coin which is 100% silver totaling a full troy ounce. This however is not a circulating coin as the silver content is worth at least 5 times as much as the face value. In the early years, when the silver content was more valuable then the face value, hoarding occurred. However, the value of a dollar up until the mid 1960s was historically significantly higher than the value of silver. Silver dollars have been minted at six locations including; Philadelphia 1793-present - Flowing Hair, Capped Bust, Sitting Liberty, Trade, Morgan, Peace, Eisenhower, Silver Eagle (no mint mark or 'P') I don't know a lot about coins: 1. I don't see a mint mark or a P mark. 2. All words and #'s can be read. 3. Silver does need to be cleaned.
