Coins of the United States
Coins of the United States dollar were first minted in 1792. New coins have been produced annually since then and they make up a valuable aspect of the United States currency system. Today, circulating coins exist in denominations of 1¢ (i.e. 1 cent or $0.01), 5¢, 10¢, 25¢, 50¢, and $1.00. Also minted are bullion (including gold, silver and platinum) and commemorative coins. All of these are produced by the United States Mint. The coins are then sold to Federal Reserve Banks which in turn are responsible for putting coins into circulation and withdrawing them as demanded by the country's economy.
Half dollar may refer to a half-unit of several currencies that are named "dollar". Normally, $1 is divided into 100 cents, so a half dollar is equal to 50 cents. Coins and/or banknotes of that amount are as such denominated at a value of 50 cents.
As of 2013[update] the face on the front of the United States half dollar is that of former President, John F. Kennedy. The Half Dollar currently isn't commonly used in circulation anymore, the government now mints this coin mainly for collectors.]citation needed[
Silver coins are possibly the oldest mass-produced form of coinage. Silver has been used as a coinage metal since the times of the Greeks; their silver drachmas were popular trade coins. The ancient Persians used silver coins between 612-330 BC. Before 1797, British pennies were made of silver.
As with all collectible coins, many factors determine the value of a silver coin, such as its rarity, demand, condition and the number originally minted. Ancient silver coins coveted by collectors include the Denarius and Miliarense, while more recent collectible silver coins include the Morgan Dollar and the Spanish Milled Dollar.

The Eisenhower dollar is a one-dollar coin issued by the United States Mint from 1971 to 1978; it was the first coin of that denomination issued by the Mint since the Peace dollar series ended in 1935. The coin depicts General of the Army and President Dwight D. "Ike" Eisenhower, who appears on the obverse. Both its obverse and reverse were designed by Frank Gasparro.
In 1965, the Mint had begun to strike copper-nickel clad coins instead of silver, due to rises in bullion prices. No dollar coins had been struck in thirty years, and none, initially, were minted in the new metal. Beginning in 1969, legislators sought to reintroduce a dollar coin into commerce. After Eisenhower died in March of that year, there were a number of proposals to honor Eisenhower with the new coin. While these bills generally commanded wide support, enactment was delayed by a dispute over whether the new coin should be in base metal or 40% silver. In 1970, a compromise was reached to strike the Eisenhower dollar in base metal for circulation, and in 40% silver as a collectible. President Richard Nixon signed legislation authorizing the new coin on December 31, 1970.
