For coin collectors who invest money in coins, the value of a coin is determined by various factors. First, scarcity is a major determinant. 21 a coin is, the more it is worth. Note, however, that rarity has little to do with the 22 of a coin. Many thousand-year-old coins often sell for no more than a few dollars because there are a lot of them around, 23 a 1913 Liberty Head Nickel may sell for over one million US dollars because there are only five in existence. Furthermore, the demand for a particular coin will also 24 influence coin values. Some coins may command higher prices because they are more popular with collectors. For example, a 1798 dime is much rarer than a 1916 dime, but the 25 sells for significantly more, simply because many more people collect early 20th century dimes than dimes from the 1700s.
