There were no Morgan silver dollars minted in 1804. The first year of mintage for them was 1878.
A authentic Draped Bust 1804 dollar is worth over Two Million dollars, but all 19 known examples are well accounted for. Many counterfeits & copy's exist, also it's a favorite for modern "Silver Rounds" made to look like the 1804 dollar.
This is NOT an original 1804 silver dollar. The value is only worth what the metal is worth. If it's made out silver it will be worth more than if it just has a silver plating with some like a stainless steel core.
If it's a fake, it's worth little to nothing.
The US didn't mint any silver dollars for circulation from 1804 to 1835 inclusive.
In 1999, one sold for over $4million at an auction, about 15 are known to exist
A real one is valued into the millions of dollars, the one you have is likely not. All 19 known examples are well accounted for. Take it to a coin dealer it may have some value if it's made from silver.
