Coins of interest to collectors often include those that circulated for only a brief time, coins with mint errors and especially beautiful or historically significant pieces. Coin collecting can be differentiated from numismatics, in that the latter is the systematic study of currency. Though closely related, the two disciplines are not necessarily the same. A numismatist may or may not be a coin collector, and vice versa.
A coin's grade is a main determinant of its value. For a tiered fee, a third party certification service like PCGS or NGC will grade, authenticate, attribute, and encapsulate most U.S. and foreign coins. Over 80 million coins have been certified by the four largest services.
