The following four factors largely determine or affect the value of a coin: First, "Things to dilute as expensive ", the scarcity of coins determines its value. Generally speaking, the more scarce a coin is, the more valuable it is. It must be noted, however, that the scarcity of coins is not necessarily linked to the age of coins.
For example, many of China's ancient coins tend to sell for only a few dollars, while the 1913 American Statue of Liberty's nickel is worth more than 1 million of dollars, because the former has a larger amount of survival, while the latter has a known lifetime of only 5. Second, the character and grade of a coin can also affect its value. The better the character of a coin, the higher the rank, and correspondingly, the greater its value.
A brand new, illiquid coin may be hundreds of times times more expensive than a coin that is character but already in circulation on the market. Third, the material value of a coin is determined by the precious metals it uses.
Gold and silver coins are usually not worth less than the original metal. The demand for coins will also affect its value to a great extent. Some of the larger coins are more expensive than those with smaller numbers, because they are more popular with collectors. For example, the number of coins in 1916 was more than 400,000, while the number of coins in 1798 was only 30,000, although the price of the former was much higher than that of the latter. The reason is that many collectors prefer coins from the early 20th century to the coins of the 18th century.
