What is the value of the most expensive coin?

For U.S. coins, it varies from time to time depending on the amount of interest in a particular coin and when it comes up for sale. Prices have leapfrogged over each other during the last several decades. The 3 most prominent rarities right now are the 1913 Liberty Head nickel, the 1804 silver dollar, and the 1933 double eagle. Some recent sale prices: One of the 5 authenticated 1913 Liberty nickels - $3 million. Type I 1804 dollar - $4.14 million 1933 double eagle - $7.6 million. This date's legitimacy has been a subject of much controversy since technically no 1933 double eagles were ever supposed to have been released from the Mint. However at least 10 have surfaced in recent years.
