Halfcrown (2 Shillings and Sixpence)
Florin (2 Shillings)
Shilling
Sixpence
The US stopped minting coins with silver content in 1965, though the dates on them were kept as 1964.
Trade dollars were US coins made in silver to trade in the far East. However, your coin, if it is an 1884 Trade Dollar, it is counterfeit. There were only 10 examples minted that year, all of them are known. So, when it comes to value, the only value your coin can have is if it is minted in real silver, if it is minted in real silver, it is worth however much silver is in your coin. If it is silver plated lead, or silver plated copper, or non-silver alloy like "nickel silver" your coin is essentially worthless.
There were no dollar coins minted in the U.S. in 1986.

Please be more specific.
No US silver dollars were minted for circulation from 1804 to 1835 inclusive, and Trade dollars were only minted from 1873 to 1885. If your coin says ONE DOLLAR and is dated 1805 it's either a fantasy coin, a bullion "round" or one of the many fakes...
