What makes a coin valuable or collectable?
The value of a coin is determined mostly by supply and demand. A coin does not need to be old to be worth more than its face value, some newer coins have extra value. By the same token, older coins do not always have value over their face value. A perfect example is the ancient coin market. Many ancient coins are rare, in the sense that they are not easy to find. Due to the lack of interest however, many ancient coins are under $50.00 in price. Why? Supply and Demand is the answer. The ancient coins are in short supply, but the collector base is very small as well.
