All About the 1804 Silver Dollar

It’s one of the rarest coins in the world: the U.S. issued very few 1804 silver dollars. And they were minted long after their face date of 1804. Only fifteen 1804 silver dollars are known to exist.

How did this all start? The records of the United States Mint show that 19,750 of the coins were struck in 1804, but used dies dated 1803. Paradoxically, dollars dated 1804 didn’t appear until 1834. These were created because the U.S. wanted to create sets of the coins to present to some rulers in Asia.

This included the King of Siam at the time, sparking the rumor that King Rama IV of Siam gave Anna Leonowens of The King and I fame the same silver dollar. According to legend, Anna passed the coin down to her children, and them to their children’s children, and so on through the generations. In the 1950’s two British women claiming to be descended from Anna sold the coin. The Smithsonian Institution displayed the coin as part of the “King of Siam” collection in 1983. They nicknamed it the “King of Coins”. In 2001, an anonymous collector bought the whole King of Siam set of coins for more than $4 million.

Class I of these silver dollars was minted in 1834. Class II of these coins was minted from 1858-1860 illegally by a man named Theodore Eckfeldt, who sold them to coin collectors from his shop in Philadelphia. The U.S. Mint tracked down and destroyed all but one of these coins. Class III was also minted from 1858-1860 by Theodore Eckfeldt, their distinguishing features including a reverse design and a lettered edge as found in Class I. Many Class III silver dollars found their way to collectors before the Mint seized the rest of them.
