Types of coins worth collecting include high-grade coins of British India, Saint-Gaudens $20 Double Eagle gold pieces with PCGS or NGC grades, and U.S. Bust Half Dollars, as of 2011. Other coins such as high-grade Barber Quarters and Jefferson Nickles prior to 1960 are worth collecting as well.
High-grade coins of British India are worth collecting because of the rapidly expanding economy of the country. Much like Americans, many people of India enjoy collecting coins from their own country, according to About.com. This makes coins, such as the silver colonial coins that the British issued when India was under its rule, valuable to collectors in India. As of 2011, silver coins in India had increased in value nearly 170 percent in just two years.
Saint-Gaudens $20 Double Eagle gold pieces are an alternative that people can buy instead of buying a 1-ounce gold bullion. People don't usually choose Saint-Gaudens $20 Double Eagle gold coins because they aren't a full ounce of gold; they are 0.96750 ounces. Investing in this coin over a gold bullion can increase a person's investment because the price of gold is likely to continue to increase and the coins may become more rare.
Bust Half Dollars are a type of coin worth collecting because of the number that the United States produced between 2007 and 2010, which led to an excess.
