In fact no silver dollars were minted in 1804. Any silver coin you find with a date stamp 1804 were actually minted in 1834 and in the 1850’s and none of them were intended to be circulated!
The reason for this was that the price of silver was rising dramatically and silver dollars were disappearing from circulation as the silver was melted down for the silver content. At the end of 1803 the US government decided to halt silver coin production with none minted in 1804.
However in 1834 as there were presentation sets of silver dollars being produced for diplomatic gifts the inclusion of the 1804 was essential to complete the sets. So several 1804 coins were struck and these are referred to as "original" or Class I 1804 dollars.
It is considered that there are only 8 genuine 1804 coins in the world although it has been thought that the King of Siam (Thailand) and the Imam of Muscat received about 10 presentation kits with 1804 coins as part of the set.
