when did the us quit making silver coins
Coinage Act of 1965 There had been coin shortages beginning in 1959, and the United States Bureau of the Mint expanded production to try to meet demand. The early 1960s was a time of increased use of silver both in the coinage and in industry, putting pressure on the price of silver, which was capped at just over $1.29 per ounce by government sales at that price. The silver in a dollar's worth of quarters would be worth more as bullion than as money if the price of the metal rose past $1.38 per ounce, and there was widespread hoarding of silver coins. Demand for the Kennedy half dollar as a collectable drove it from circulation after its debut in 1964. The Bureau of the Mint increased production, helping reduce the coin shortages by May 1965, but government stocks of silver were being rapidly reduced, and threatened to run out by 1968. After extensive study by the Treasury Department, President Lyndon B. Johnson in June 1965 recommended that Congress pass legislation to allow for silverless dimes and quarters, and debased silver half dollars. Although there was some opposition, mainly from legislators representing Western mining states, the bill progressed rapidly through Congress, and was enacted with Johnson's signature on July 23, 1965.
Coin Coins may be in circulation with fiat values lower than the value of their component metals, but they are never initially issued with such value, and the shortfall only arises over time due to inflation, as market values for the metal overtake the fiat declared face value of the coin. Examples are the pre-1965 US dime, quarter, half dollar, and dollar (nominally containing slightly less than a tenth, quarter, half, and full ounce of silver, respectively), US nickel, and pre-1982 US penny. As a result of the increase in the value of copper, the United States greatly reduced the amount of copper in each penny. Since mid-1982, United States pennies are made of 97.5% zinc, with the remaining 2.5% being a coating of copper. Extreme differences between fiat values and metal values of coins cause coins to be hoarded or removed from circulation by illicit smelters in order to realise the value of their metal content. This is an example of Gresham's law. The United States Mint, in an attempt to avoid this, implemented new interim rules on December 14, 2006, subject to public comment for 30 days, which criminalized the melting and export of pennies and nickels.[30] Violators can be fined up to $10,000 and/or imprisoned for up to five years.
